I'd be fine if they reverted all the nerfs to Yasuo lane phase if they made his double crit passive

Darius has no gap-closers unless he pulls you so you can kite easily, veigar has no escapes and low mobility with only one cc ability, and lux has decent cooldowns+weak aa's+ no escapes besides CC.

Yasuo has gap closers, escapes, passive shield, extra-wide braum shield that starts on him and blocks things including ults and hooks from both directions, built in crit and armor pen, a skillshot that goes through minions and can hit the whole enemy team as well as go through terrain. Overloaded champ.

"Oh, just pop his shield." If you're melee, you lose the trade because you pop it while he hits you, then dashes away while hitting you some more. If you're a marksman, you can do it from range, but he can also dash to you then out-trade you.

"His wall has high cooldown." Yeah, well by the time I catch him again and my abilities are up, his wall is nearly up again, and I'm still damaged from last trade.

Too much mobility and damage for someone with that much sustain. Take away something.
