think ive figure out the core of why Yasuo is so Annoying, its his passive shield and ability to just sit on your face and just 2X Q you then knock you up leaving little room to react. Riot has stated that it can be unhealthy for melee champions to ONLY be about getting on a target and sticking to them no matter what to deal damage, thats why recent melee champions have been given ways to encourage them to his at a distance. Yasuo can and will stick as close as he can to a target to damage them, and his 3rd Q, in addition to E affords him the stickiness he needs. If his 3rd Q encouraged him to move back to get the most out of it it would offer opponents a chance to breathe against the slew of not only damage but CC and defense that he can put up.
Ive come up with some appropriate changes
Yasuo: 3rd Q only knocks up a little or not at all at close range and more at max range.
R deals damage based on the amount of time the targets have spent in the air. Basically the higher they get knocked up the more damage it deals. Yay more skill!
Another reason Yasuo feels unfair IS the amount of defense he has for the damage he can put out. His passive shield is especially annoying for a few reasons, unlike other champions he doesn't have to cast abilities (that normally cost something) or hit enemy champion to charge it, he just has to move which can be considered uninteractive since the opponent doesn't get to do anything about it. Also it doesn't feel skillful for the Yasuo player to get the shield, all he has to do is move around, now sure you can move around alot to charge it at the last second IF there are enough units near by...but does is moving around using E or right clicking REALLY all that skillful? Not only that but if a Good Yasuo player IS moving around using E or moving they can ALSO use that to dodge skillshots/avoid enemies, and then they have a shield that they can use to tank the next ability or AA, and its passive so Yasuo ALWAYS gets to charge it, and theres NO CD. And once its up it stays. AND tower shots don't even make it go away, not saying the shield should block a tower shot, but its weird that Tower shots dont just destroy the shield. Other passive shields are just consumed based on the damage dealt to them and dont stick around once destroyed.
his passive, W, ult to refresh passive (and keep him out of tower range, this is TOO much safety for all the damage he can dish out, he gets to play like some sort of situational tank)
his passive should should just be deleted instead Rework W so it has a longer CD but it gets reduced by moving and change it so it acts more like a directional spell shield (its up for 0.75 sec and then its gone).
less annoying + a bit more skill = less skilled people playing Yasuo + less hate
