With all the tenacity runes available, mercury treads and elixir of iron, you can get 76% tenacity.
And you can get rooted / stunned by champions like Morgana, Nautilus and Veigar for approximately 2 entire seconds.
Are you telling me 2 seconds is 24% of the full duration of those crowd control effects?
Arisen Valkyrie25 votesiirc tenacity does not stack additively (barring a small number of combinations), but rather stacks multiplicatively. So no matter the amount of tenacity they introduce it would be impossible to get 100% tenacity. For instance Garen gets 60% tenacity just from his W alone, so Legend Tenacity+Mercs would put him over 100% if it was additive.
BlackKnightJack3 votesThis is indeed how it works.
Slythrin Umbreon2 votesOn top of that, the tenacity rune in Precision stacks up over time and the other one is situational, so you're not going to get the full benefit all the time.

I don't know why you guys are preaching the OP on math when he did it (almost) correctly. Maximum tenacity with Legend: Tenacity, Mercury's Treads, Unflinching and Elixir of Iron is 75%: 0.7*0.7*0.68*0.75 = 0.2499

(With Slow Resistance (which stacks additively), however, it IS possible to exceed %100, and at that point slows will speed you up.)

Its because they have no tenacity at all?
With merc threads+legend:tenacity you´d a case looking like this :
Stun duration reduced by merc threads then that amount reducerad by Legend:tenacity.
((3 seconds * (0,7)) 0,7* ) = 1,47
Or for absolute clarity.
3 x 0,7 = 2,1 (first tenacity reduction)
21 x 0,7 = 1,47 (second one&final duration)
Is 1,47 a long time? Fairly so i´d say, but not really OP or UP.

It kinda has to with every champion coming out with 8 dashes 3 blinds a stealth a backflip and a blowjob
BlackKnightJack13 votesAs someone pointed out, tenacity does not stack additively. If it did it wouldn't actually be that hard to get over 100% tenacity and become completely immune to crowd control. It works multiplicitively. Here's how you calculate it:
Morgana's Q is capable of rooting someone for 3 seconds at rank 5.
You have 
Mercury's Treads. Its ability lowers this duration by 30% meaning only 70% of that 3 second root applies (which is 2.1 seconds)
On top of Merc Treads, you have a fully stacked Legend: Tenacity rune. This lowers the duration of the remainder of the root by another 30% as it is a different source from the Merc Treads meaning the root will now only last for 1.47 seconds. By contrast if tenacity were additive then the root would last for 1.2 seconds instead.
It took me a while to figure out how this works, too. Like armor, additional sources of tenacity give diminishing returns and as such there isn't really much point in stacking all the sources you can get your hands on unless you're having a MASSIVE problem with the enemy locking you down with all of their CC. If you're, say, 
Darius, then Merc Treads and 
Sterak's Gage should be all the tenacity you need (With an Elixir if those two are still not enough).

Oh god. People like this make me cringe so bad. "that things are working?" it's like they think everything works on this game all the time, when league is the buggiest damn game I have ever encountered in like 20 years of gaming. It's kind of ironic because we all see all these bugs and glitches on the surface...people going through walls, THE CLIENT (buggiest piece of software on this planet probably) and all the BUG FIXES which is proof there were bugs, but listen to this...this part will blow your mind. If they can't even get visuals right, imagine how many bugs there are beneath the surface that YOU can't see? Mathematical / variable errors, wrong numbers / bad math, etc.? When is the last time you saw a bug fix for something like that? That's because you can't see it so they don't tell you about those bugs...they just fix them when they can and keep quiet. Yet you always get THIS type of person in the forums "things are working obviously hurrrrr". No, you just lack the intellect (or programming experience) to see what others can see. We see beyond the surface to the functionality of the game. I would imagine the people with programming experience...or a high IQ? IDK but some people see this stuff and MANY others don't. You all seem to think a video game is just this magical thing which appeared and works perfectly as it should. I made an entire game myself in my early 20's, (a mobile game similar to angry birds which was pretty much a failure BUT IT WORKED PERFECTLY) and I know what goes into this shit. That thing took thousands of lines of code and was less than 1% as complex as something like League of Legends. So if you think things just "work" man you don't know shit about game development and should just not comment on stuff you don't understand.
BlackKnightJack5 votesHe's not making it up. He just doesn't understand how tenacity works.
murchalvias21 votesI have zero clue why you're being downvoted. This guy is straight out claiming that Morgana root takes "approximately 2 entire seconds" with 76% Tenacity with no proof whatsoever. His claims are simply not true and make no sense, anyone can go test it right now in a custom game and see that it takes around one second. Maybe he misunderstood how Tenacity works, but even then it does not take two seconds with Merc's + Runes.
Lovelle10 votesI've never noticed a difference with it, but I do notice when I don't take Bloodline or Revitalize, even in the early game.
BlackKnightJack1 votesI use to take Legend: Tenacity on Darius all the time, but was frustrated with my lack of damage and switched to Legend: Alacrity and have definitely noticed I do a lot more damage. Would make sense I don't notice the lack of the tenacity rune since most CC doesn't last long enough for it to do much on top of Mercs and Steraks.
Lovelle2 votesYeah, I would rather have the lifesteal from Bloodline as I play a lot of Trundle and he gets enough attack speed from his W, but fitting lifesteal into his build is hard without sacrificing durability.
If burst damage wasn't so crazy then tenacity would probably feel a lot better as a stat.
Judah Bot7 votesAny champion can get %77 Tenacity from mercs, Legend:Tenacity, Elixer of Iron, and fully stacked Unflinching. (This will just begin to scrape the .5s Tenacity hard cap on a 2s CC.)
Without the Unflinching it's still a reliable %63. We haven't bothered to include Sterak's procs, or Cleanse.
That's %63 Tenacity from 3 sources that are pretty easy to have all together by midgame.
Smite DOES proc Unflinching. You can maintain a fairly consistent (well, on-demand, but easy to get) %32 Tenacity without mercs, just by running Unflinching and Smite.
The %10/%20 component of Unflinching does stack additively with Elixer of Iron. One advantage of Unflinching is that you have full use of it lvl 1. Legend Tenacity probably takes about 12m to fully stack.
Nanuk Pihoqahiak4 votesTenacity Runes don't start off fully stacked, and you won't have Elixirs of Iron until super late game. Having all three at once is highly unlikely.
PiVoRx4 votesTbh i found buyng tenacity pointless.. With this ammount of cc we have in this game, it doesent make any difference. You will get hit by 1 cc, there will be more on the way, and even 1-2 seconds of being unable to move is death sentence.

Nea1042 votesWhatever they work, they look pretty underpowered, as the current (2 year old) burst meta establishes.
Clown Parade2 votesThe reason Tenacity is worthless is because so many CC abilities aren't affected by it at this point.
Same reason resistance stats have become less valuable over time, as there's an over abundance of true damage in the game.
BlackKnightJack2 votesNot necessarily. A little bit of tenacity can go a long way, but only a little bit. The problem is diminishing returns makes it pointless to stack.
RazorScythe1 votes[deleted]
Garen Nightmare10 votesIf I remeber right mercury treads and elixir of iron don't actually stack.
Now if that isn't the case then the cc is just lowered by -0.76 seconds.
Morgana per skill point: 1.24/1.49/1.74/1.99/2.24 seconds a root Nautilus per skill point: 0.24/0.74/1.24 seconds a stun Veigar per skill point: 0.74/0.99/1.24/1.49/1.74 seconds a stun
They stack. They all stack, but mostly only multiplicatively.
That they stack only multiplicatively for the most part, should tell you, that Riot considers Tenacity to be a broken stat.
Mercs + Sterak's are additive.
Iron + the initial %10/%20 bonus from Unflinching are additive.
TakaDama2 votesThis actually helps a lot ... already knew that multiplicative was how they were calculated before (even believe there were some patch notes regarding that), but since those two sets are additive, that changes things.
For example, while in the the OPs example without Sterak's Gage the tenacity would be at 47% max (two summoner's activated for Unflinching), with Sterak's Gage that becomes a whopping 94% tenacity.

My reckoning is: Steraks, when it activates, will give him +%25 additive to mercs only. So, assuming he has fully stacked Unflinching as well as Legends, %55 x %30 x %15 x %45 = %85 Tenacity. Considered to be virtually Unstoppable, but Steraks is a bit wonky (you don't really have control over when it procs) and this assumes a fully stacked Unflinching, which doesn't come up often without Smite. At this point, you probably run afoul of the .5s Tenacity soft cap...
With consistent tenacity sources: Legend, Mercs, Iron, then you still have quite a bit: ~%63 by midgame, and not very difficult to acquire. You basically walk right through Veigar Cage with that.

The Tenacity cap is not %51. You can stack it as high as you want, but the CC will not get reduced below .5s (unless as you say, an innate Tenacity ability is active).
Nasus has a 5s slow. You'd need %90 tenacity to get it down to the soft cap .5s.
Illabethe1 votesThe problem is that most tenacity sources do not stack additively.
I'm not saying there's a cap. I'm saying that without extra skills, rune investment, the general max is 51%/63% if you have Elixir of Iron. Mundo/Garen can get higher and Unflinching + Legend: Tenacity can get a little higher, but not much.

If you've been reading, any champion can get consistent %63 Tenacity by midgame from just Legend + Mercs + Iron. Adding Unflinching could get that to %77. Bringing Cleanse and having anything else makes basically unstoppable for a few seconds.
Mercs and Iron alone is pretty common and that gets to %48...
