I'm very consistent with Moira and Reaper. I used to main D.Va, but her recent nerfs make her feel like her damage just barely takes too long to kill an opponent for my taste. I've played Torb jokingly long enough to the point where I'm actually pretty good with him.
Hanzo was a favorite of mine until the changes. The new velocity of his arrows makes him closer to a hitscan, which on the surface makes him seem way better than he was. However, the previous arrow speed was exactly how I thought his arrows should work, so the change has really upset my ability to play him. I'm still okay, but way too inconsistent. The rapid shot and leap are amazing, though, but as I said, it's hard for me to take advantage of the rapid shot because the speed of the arrows is too disagreeable with me right now. Haven't gotten used to it.
