got its crits nerfed from 25% to 20%, so adding up with the everyday purchase 
which is 20% as well, a total critical chance Yasuo will be receiving will now be 80%.
So there you have it, one small nerf on the broken crit-ass champ. Not much, but it's still something.
well its a nerf obviously, but in my opinion its not that bad,we can now build phantom (30% crit chance) and infinity adn we'll have 100% which is in my opinion even better
I think this might change Yasuo a bit. Now you don´t have to take crit runes but you can build IE, Statikk and Trinity instead if you want to reach 100% crit which is pretty useful for Yasuo.Of course it´s gonna be a bit expensive but, .. just my opinion. :)
Stick with the and and get a 
as well = %100 crit and double damage on q and even more attack speed.
Just Run 10% Crit Runes and you're good
