@TyldaaI agree that on the surface it seems unfair. Having come from shooters where all players are the same size, speed, height, etc. it can feel annoying to come up against a wraith with a postage stamp sized hitbox, or a Gibby with a 10% damage buff.
On the other hand, part of the sport of this game is all the endless variation, including legend variation. I have to think that if Wraith's hitbox advantage wasn't counterbalanced by so many other factors then her pick rate would be through the roof. But it isn't, at least not anymore. I know pick rates don't ever tell the entire story, but they give a pretty good indication of whether or not things are seriously out of balance and by how much. So far I'd say they're not pointing out any major problems.
That said, after 22k matches I still dread close-quarters combat with a Wraith. I guess I always will.
