When i play certain champions i like to run precision for the tenacity rune. This yields 51% tenacity with mercury treads.
However, after the patch Tenacity seems to no longer work. Disable durations no longer seem to be reduced at all, even should you bump it up to 70% tenacity with an elixir or resolve's unflinching.
Warlord Rhinark27 votesAs if Tenacity ever worked.
ModCaptainMårvelous8 votesWell, it did when there was longer base CC and more "normal" CC. 25-40% off a 3 second stun is a pretty big deal. Now there are knockbacks, displacements and more which CC does zip against along with standard CC being reduced to 1-2 seconds, which means 30% off 1.5 seconds doesn't feel like anything.
Axzarious2 votesWTB Tenacity buffs. It can be pretty tough to justify it sometimes, unless there's a ton of enemy Magic Damage on the team. Even then, I've still went with Tabi because it ends up cutting more total damage while I'm CC'd anyways.
Z3Sleeper1 votesYeah Tenacity is a dead stat. It's just that thing that's kinda nice to have but noone really goes out of their way to opt into unless against a heavy "normal CC" comp.
Like, bruisers are gonna build Steraks regardless and people are gonna build Mercs vs massive magic damage comps, the Tenacity is just kinda there.
Mordepool1 votesEven against Stun comps it seems an irrelevant stat. Just had one of those games
Mordepool1 votesThey should reduce the duration of all cc that is unaffected by Tenacity.
Furious Delisha5 votesOh thank god it's not me going crazy. just a while ago i was playing garen into Zoe. Even merc tread + timed W didn't get me out of sleepy bubble in time. Thought it was REALLY strange that cause it should be about a 75% reduction in sleep time.
Emerald Fang1 votesTenacity doesn't affect sleep; it's a unique form of CC
Rathar Dashing2 votesThe duration of Drowsy can't be reduced, but the actual time spent asleep can be reduced. You can lower Zoe's 2 second window to land her Q down to a 1.4 second one, with just merc treads OR legend:tenacity. Both gives her less than a second to land it. Really frustrates the Zoe. Slow resist also reduces the effectiveness of the slow, but it's not really powerful enough to ever warrant getting swifties.
ADC Yuumi4 votesI've noticed the same too, I usually do a full tenacity build for any support I pick; but I seem to still be in a Lux's Q for the same duration.
xDogMeatx13 voteslux's q feels like a morgana root at level one.
Support 4 Lyfe5 votesIt is, they have the same duration at rank 1.
Ceazaru3 votesHasn't Tenacity been dead?

tenacity is noob trap unless is vs nasus w
I was playing vs Nasus. It had 0 effect on his W.
Lemonfaace2 votesIt speeds up the slowing so it can end faster. You’ll still feel it, but it should end sooner.
Axzarious1 votesSwiftness boots reduce slow severity, but it doesn't really feel all too different from treads either way. Often, you'll be better off with Tabi anyways due to the damage it will shave off his Q.
Emerald Fang1 votesIt only has effect on the last slow increment since the slow is perpetually stacking, so it can't be reduced until the last one.
AlienPrimate1 votesBoots of swiftness is a much better choice against Nasus. Tenacity is still a great stat against all of these 
Metallikaiser1 votesI definitely Garen w'd through most of that Morgana bind, so no, it still works for me.
Gall1 votesI only notice it when I play veigar into people with merc treads, but even then it's only about a second or less difference with the E stun against people with the boots than without.
BigFBear1 votesWhy not just check it in practice mode??
Aatrox Airlines1 votesWhy not just check it in practice mode??
against what? bots?
Rathar Dashing2 votesUhh, yes? What else? Throw on a Morg bot on intermediate and see if her Q roots you for 3 seconds or 1.5 seconds.

or make a private game with a friend
Rathar Dashing1 votesTested it out in practice tool, seemed to work just fine. Made it to 63% tenacity and had morg Q root me for just over a second.
Emerald Fang1 votesMaybe bc there's overwhelmingly more knockups in the game than any other type of cc. It might just feel like it isn't working just because there's a lot of knockups.
Mordepool1 votesTenacity: a Joke stat waiting for deletion.
