Wait wait.. Zyra buff??

What? How can you seriously sit here and tell me there's nothing wrong with Zed's kit? He's got like a 40% winrate and still one of the highest banrates because people just don't want to play against him. That's a hallmark of poor champion design right there - something shouldn't be so awful to play against that he's banned IN SPITE of his strength instead of because of it. Because no matter how weak Zed is you can't seriously tell me he has "clear counterplay" when he pushes R on a carry, pushes E Q and then W's out and oneshots them instantly. At least Talon has to use his blink to get into the fight (and it has to target enemies), at least Katarina has to get a kill BEFORE she has her escape, but Zed literally doesn't care if he successfully kills his target - no risk, so whatever the reward is is fine. Zed isn't strong right now but that doesn't mean by any stretch of the imagination that his kit is fine. There is a difference between "broken" or "overloaded" and overpowered.

Also I fail to see how Nidalee or Azir are even remotely in the same vein as Yasuo. Nidalee has no ultimate so she's already playing at a disadvantage, and couple that with the fact that all of her melee range abilities are empowered by a long range skillshot. Her kit has clear counterplay and ways to stop her getting in - and most of her damage comes from actually hitting skills (the Q execute relies pretty heavily now on the mark to really do considerable damage unless they're already really low).

Now compare that to someone like Yasuo. Literally nothing in his kit requires him to interact with you in any way to prepare himself to fight you. He can stack his Q on minions to get the knockup (0 interaction with his enemy laner), he gets a double crit passive literally for free (he doesn't have to do anything to access this power) and, again, he gets a shield literally for running around the map. I don't have a problem with Yasuo's base abilities really by themselves, but the fact that he has a passive that doubles his crit chance and then ANOTHER passive that gives him a shield is basically the textbook definition of overloaded. If a character only works because you gave them two passives where normal champs only get 1 (or have a passive attached to an ability), Yasuo just gets two passives. If his crit bonus was on an ability (for example) and scaled with skill level? Suddenly not overloaded. Put his shield on another ability and make it skill level dependant on how strong the shield is? Suddenly not overloaded. But when you start the game with your major steroid not only available to you but available at full strength, it's overloaded. There's not a single other character in the game who has their steroid attached to their passive that is the same at level 1 as it is at level 18. Trist gains attack range, but it's based on her level. Jinx can get increased range on rockets/AS on minigun, but it depends on skill rank.

Yasuo's kit by itself is suspect anyway (manaless champions with short cooldowns are a bitch to balance), but when you add the fact that he has a double passive and one of them is at full strength at level 1 it gets silly.
