I've figured out why Yasuo is too strong
It's because of
's passive.
Back in season 5 and earlier, Yasuo always built
as his first item. Ever since the marksman rework when Phantom Dancer was changed, Yasuos started to build it more and more. After that
build cropped up (back when Trinity had crit) it was here to stay.
Phantom Dancer's passive is too strong is the problem. It gives 12% reduced damage while giving more attack speed than all the other zeal items. A 12% damage difference between you and your laner at ONE item is ridiculously powerful. That's the equivalent of fighting someone that has 1.5 Infernal Drakes when you have none.
Yasuo should win lane and be strong because he outplayed his opponent, not because he's stat checking them with insanely strong damage reduction that in no way affects his damage.
Should Yasuo be able to build
? Of course, he has the right to make that choice, but right now it's too strong. This is exactly like what happened to
(an item gives too many stats and serves as both offensive and defensive with no downside). It needs either it's attack speed reduced to make it more defensive, or it needs it's Lament passive damage reduction to be reduced.
in there and give him crazy sustain as well.
