: They just won't stop healing!
:

It's funny that you put draven in because it's gotten to the point where he's the equivalent of a warwick in driantanking.
Nah, WW doesn't heal nearly as much.
*Sometimes I feel like the only person who builds 
i build it over
when the team is heavy healing as it would be better than lord dominits in that regard
more cause hes the healiest (is that a word?) adc
Oh, classic mother.

Add
, the carry will never die
Carries can die?
Havent seen it before tbh

You guys are forgetting something
Forgot this. A real Zil never forgets it
When your team complains that the enemy team heals and lifesteals too much but no one built

I've had to semi-regularly build Executioner's Calling on tanks because nobody else bothers to pick it up.
It's quite sad.
I'll be so glad when the new Thornmail comes out with Grievous Wounds... on it's component item!
Unfortunately, I might still have to purchase Executioner's Calling.
Something tells me that Swain isn't going to bother autoattacking me during teamfights.
I've been playing more tanky champs (especially Sejuani) and I don't like sacrificing that tankiness since I'm usually the only tank on my team. Whenever I see that a champ on the enemy team relies a lot on lifesteal or there's a Soraka I'll immediately suggest that our ADC build mortal reminder (ex. "hey trist, they have a draven so it might be a good idea to go mortal reminder")
"hey trist, they have a draven so it might be a good idea to go mortal reminder beat yourself to death with a baseball bat IRL, it'll hurt less."
There, fixed it for you.
you're right
Oh, I'll suggest they build it.
They simply don't.
THEY ARE JUST TOO FAST! 
My spells aren't making a dent!
People often forget that it's generally harder to build Mana resistance and keep yourself tanky against AD damage. Because Most mana resist items do not provide Attack Stats or large pools of HP. The other thing is... people generally misunderstand just how much more powerful building penetration is then just more damage against a target with a high armor or resistance. Look at the math of Magic Penetration Teemo.
I can only hit one target at a time!
They blow me up too fast!
I can't split push! They need me in a fight!
I'm squishy! I can't afford to build armor! or I will loose out on AD!
I can't get close to that bush without risking getting jumped by Rengar to place a ward!
I have no escape! I need a wall in front of me or I will die!
GG SORAKA NO HELZ

Gosh darn that mana resist. I don't have enough, causing my spells to burn all of my mana!!
Okay, but let's be honest:
is garbage for the very same reason
exists, Riot has decided that the only ones who can deal with tanks are ADCs. Mages should be building
anyways in order to be able to scratch tanks, but a cooldown-based champion will always have issues against a guy who is a bag of resistances and health.
If your ADC isn't building Armor Pen then yeah, he sucks, but that's just the carry being bad at the game, it happens in League of ADCs very often and you just have to deal with it and move on to the next game.
I hear
needs
instead, now that he deals mostly magic damage
He's always needed it from since they did the half and half damage. Now people know its mandatory.
Honestly, even before the rework he did slightly more magic damage than physical.
His passive made half of his autos do true damage. So back then I'd say that LW was still a good choice.
BOTRK-select few build it Liandry-viable on a few champs Last Whisper-nerfed into trash teir.
You ignore the massive level and gold lead they probably have and the fact yuor team is 5 early game squishies.

True, but you can always just get EC on the ADC for 800 gold. You're only giving up bonus crit or damage at that point, in exchange for having the damage matter more.
Why would you build liandries for pen, build a void staff.
litterally anyone meta rn builds BORTK.
If last whisper is trash, then UPGRADE IT if the enemy team is too tanky then lord dominiks will probably be a good choice.

Excellent meme, 10/10.
when your team complains about getting oneshotted by teemo
(yes all in the same team)
:
gA Is sElFIsH
"hey guys there team is super tanky get some % of health damage items"
-team gets stomped as no one builds anything- "HOW DID WE LOSE!"
Arthur memes are still better than Spongebob memes
Uhh... just to give a complete list...

While Lethality is less effective against true tanks, it's still solid armor penetration.
Lethality is actually less cost effective than flat ad against high armor targets. As you get more armor, the damage reduced becomes less. Thus, as your target has more armor, the effect of lethality becomes less. I just made a chart using gold costs of lethality and flat ad when attacking certain numbers of armor. Here are the results assuming bases of 0 lethality and 100 AD. AD translates to the same exact damage multiplier against the target no matter who the target is. Lethality changes based on how much armor the target has.
500 gold spent gives 14.5% damage from ad
50 armor target Lethality gains 17.4% damage
100 armor target Lethality gains 12.5% damage
200 armor target Lethality gains 8% damage
300 armor Lethality gains 5.9% damage
1000 gold spent gives 28.5% damage from ad
50 armor Lethality gains 42% damage
100 armor Lethality gains 28.6% damage
200 armor Lethality gains 17.4% damage
300 armor Lethality gains 12.5% damage
Now if it is late game and you already have 250 AD
500 gold spent gives 5.7% damage from ad
50 armor target Lethality gains 47% damage
100 armor target Lethality gains 45% damage
200 armor target Lethality gains 43.2% damage
300 armor Lethality gains 42.4% damage
1000 gold spent gives 11.4% damage from ad
50 armor Lethality gains 56.8% damage
100 armor Lethality gains 51.4% damage
200 armor Lethality gains 47% damage
300 armor Lethality gains 45% damage
As you can see, lethality is more effective against lower armor targets, but if you already have high amounts of AD, the gain from lethality is way higher. A balance of both will give you the most damage. Stacking lethality or AD isn't nearly as effective as building both. If you just build lethality against high armor you won't gain hardly anything. If you build it against a low armor target you will gain a lot. If you stack them both though, your gains against both types of targets are massive.
Okay... So... Yes, you're quite correct on ALL of that.
But again, it is still armor penetration that would work against anyone with less than 2 armor items.
total out to 45 lethality. You get 40% or 60% up front, getting the rest per enemy level. Add 24 Lethality you can get from Runes and that totals out to 69. 40% of that is 21 (rounded up slightly), which means minimum you're ignoring 21 flat armor which is more than
and only scales higher.
are the only two items with more than 69 armor. Lethality is strong as long as target enemies don't have more than 1 armor item.
And let's face it, one armor item is often enough to help a bruiser survive long enough to get on top of the ADC and murder him.
Point is that it's a means to keep enemies from being too tanky after a single item.
As a first item for both people flat AD will still way out perform lethality though. When talking first items, you will likely only have about 70 AD rather than the 100 I used for the example. Getting your AD up first will benefit you a lot more if your enemy builds armor first item. If they don't build armor first then yes, lethality is better.
