As an Irelia main I'm facing a lot of hate towards the 2 second stun from ADCs. What I don't understand is why they don't just buy Merc Treads? 35% Tenacity would lower the stun duration down to about 1.3 seconds and in lategame it's even somewhat a challenge to burst them down in the 2 second stun. I just don't understand this logic, do 25% attack speed really do that much of a difference DPS whise?
Linna Excel2 votesADC mains are babies. Most ADCs don't really scale well with AS, though a few do. Part of the problem is they don't like to or know how to build for the situation.

Linna Excel1 votesThey can get other items for AS. I never get zerkers on Jinx because I'm usually getting BORK on her and if bork/shiv isn't enough hurricane works well on her. Not that she needs it for her minigun. Now if we are talking about maximum rockets, get her a hurricane.
Seth Lightheart2 votesYes and No. If your AD went 100% tank items it would make them way more tanky too. But the bottom line is there is a balance (as you already know), and the opportunity cost of not buying 
is too great. To help relieve this you need a support to help peel.
thunderingice1 votesthis. also, quicksilver is a far better choice for adcs than merc treads.
Myrmiron2 votesSo you're going to use quicksilver on a 2 second stun that has an 8 second cooldown? IMO QSS is only worth it against Lissandra, WW and Malzahar.
el PepE hanDs 2 votesSo getting out of a two second stun is useless ?
Angry Monster2 votesyour missing the point. If the adc is using the QQs its to get to safety. Who cares if your stun is 8 sec. IT give a fighting chance at that point and if you have good reaction time you can have it popped in .5 sec. better than the merc. Plus builds into a DPS item
are you bronze bro?
Myrmiron1 votesNo I'm not, I'm just saying that buying QSS and using it on pretty much nothing else but a 2 second stun is about wasted if you're not completely out of position.
Stephenizgod2 votesIt depends on their team comp, that 2 sec stun can turn into your entire team jumping on them, its better they get away as fast as possible, plus it gives other useful stats to ADC's.
Angry Monster1 votesSigh you got to be bronze, cause fights do not normally last that long. You are saying that in a fight where the adc could of Locked down by CC that using a CC removal to fight and not fall down in 1 sec is pointless.
are you even thinking things through?
Myrmiron1 votesI encourage you to look me up in lolking if you actually think I am bronze.
Sir Yamazuki2 votesSo you're going to use quicksilver on a 2 second stun that has an 8 second cooldown? IMO QSS is only worth it against Lissandra, WW and Malzahar.
Unless you're slow, it would mean the stun would be shorter than if you had mercs, builds into something that gives AD, so it means you're not giving up damage either, and Ireia should be dead before she can stun again anyways...
Ale non è male1 votesQss builds in Mercurial, aka damage item, so nothing negate you to build both Mercury Treads and Mercurial if enemy has a lot of much CC in their kit. Just saying
thunderingice1 votesIf an adc does his job right he should not be taking more than 1 or 2 ccs in a fight. There are exceptions, but getting ccd is death generally. Reducing that cc by a third doesnt change that against good players. If you needed to use your qss twice, most likely you screwed up. There are exceptions to this. If your team, esp your support doesn't peel for you, you probably cant get as close to the fight as you need to without dieing. If the enemy team has a super heavy dive team, it's possible that they get to you like crazy. In that case, you position so that they have to suicide to get to you. etc. there are probably a couple more that I havn't considered. But in general, the ability to escape the first cc that hits you is far more valuable to an adc than having it's duration reduced.
I regret that this thread turned into bashing, but well, it seems like the g and b board has even more nonsense on it than old GD did. I don't see any of the people who used to give good insight as authors of threads. oh well. Anyway, I did look you up. You are obviously not bronze. You are however, obviously a specialist. I would be keen to hear your opinions on irelia any day of the week. Adcs play a tad different though. Anyway, my main point is that reducing the time on cc by a third is not very valuable for adcs. Instantly removing it so that you can keep kiting and repositioning as the fight continues is. I hope that helps.
Edit:For the record, I refuse to defend the adcs you are playing against. Let them complain. Irelia is in a decent place right now, but I can name 4 top laners off the top of my head who I am pretty sure are stronger.
SmokingPuffin2 votes25% AS usually will mean about 15-20% more right click damage.
An ADC that builds tanky stuff is a pointless object. The whole point of an ADC is that they can stay alive with positioning, rather than defensive stats. If they can't do that, better to pick a more durable class to start with.
ZephyrDrake2 votesbecause they will die anyways whether they build 
or . ADCs build 
because they can instantly get rid of any cc that do manages to get to them therefore actually being able to survive and dish out damage
ChaoticPinecone1 voteson the ADC side, i would say because they buy Bezerkers before teamfights really happen. by the time they realized that you are jumping on them (not the Mid), and the team doesnt peel, they already bought their tier 2 boots.
on your side, I dont understand why they dont get the Zephyr. Its a great item after your LW, especially if youre dying too much from being CCed. A Bloodthirster doesnt help if you die before autoattacking.
Drukyul1 votesA Bloodthirster doesnt help if you die before autoattacking.
Yeah it does, that's the whole point of the shield.
thunderingice1 votesthe shield is the worst part of the BT. bt was useless until they buffed it to the point where it was good without the shield.
Angry Monster1 votescause it only has only 25 AD
thunderingice1 votestenacity is only valuable against teams with low cc and low dive when you are an adc. otherwise, decreasing a cc from 2 to 1.3 seconds doesnt change how dead you are. qss does the job better and costs less and when upgraded to mercurial, gives more useful stats. and for the record, if an adc doesnt expect to get dived, he is either naive or having a really bad game or is at low elo. getting dived is not a surprise.
Sire Hippington1 votesdepends how far in the game you are. in the early and midgame, zerks are actually quite needed, the higher as helps alot at farming and trading in lane due faster animations ontop of faster attacks, and the dps boost it offers for the midgame is pretty valuable. In the liate, it probaby would be better in many situations to have mercs, but on the otherhand you often will either have quicksilver or zephyr doing the job better at that point.
