Mhm, I remember back then Hanzo being barely used and considered a troll pick. Widow and Dive still counters him (well, yeah, I concur Widow is not really "counter"), although slightly less effective because of Lunge and Storm arrows.
We get to see new heroes being played, new comps, and that's healthy for the game. In my opinion. Soon Symmetra changes will kick in, and maybe the meta will shift again.
