Aatrox needs to have his role defined.
He's this hybrid tank diver thing. He has too many tools for certain classes. Too much CC to be anything but a tank. But too much scaling and damage to be anything but a fighter. He needs a CC component removed or changed to a slow.
He has as as more CC than many tanks, 4 hard cc
Graves: 1 of several options: Remove monster knock back (he still gets it vs minions), crush his defensive steroid, nerf his movement speed. These changes are all targeted at making clearing the jungler harder.
Given he scales like a god, rules the early game like a god, has AOE/single target burst like a god, tanks like a god and then gets to clear like a god. He needs a downfall. He can't be not just good, but god tier at pretty much everything.
Personally I favor removal of monster knock back because other ranged jungler don't need it, so why the fk does graves when he is tankier and more mobile than most of them?
Akali: Let's be honest. Very few people will ever enjoy dealing with her as long as her shroud exists as it does. Most of her kit is fair, very fair.
So I'd make a few changes: damaging akali while in shroud reveals her for longer than current, successive hits keep her exposed for less and less time. Shroud no longer restores energy.
Potentially remove the mini stun from R
Irelia: Cap Q damage against minions and reduce the animation speed. She's like 4 times faster than yasuo E and as a lategame hyper carry, she should not be able to last hit so effortlessly so quickly. Are we 30 minutes it? Sure. because most champs can do that. Before that nah.
Potentially also remove the dmg reduction and reduce the animation speed of W?. Over complicated spell tbh
Urgot: needs no changes. Not an urgot main but the issue is no one understands urgot.
He is anti dive. What is everyone picking? Irelia, camille, renekton, jax, noc, eve ect ect. So I wonder why urgot is so strong? perhaps because everyone keeps counterpicking themselves?
Already posted a longer explanation so Find in page my name for that. Moral of the story is that you simply have to play differently vs urgot. There's nothing inherently wrong with him at the moment.
Kai'sa: honestly don't know. Don't pay enough attention to her. Nerf her missiles like crazy I guess? given it's auto targeted dmg
