Hawkeye needs improvement
He is too simple for the time being, which many champions with awesome stuff have jointed the contest.
He is the guy with bow and arrow, but not only that, he has many kind of arrows. But in this game, all he does with his arrows is bleeding enemy. Yes, that's nice but he should be capable to do more since, as many of us know, he has many tricky and special arrows. The animations you have for Hawkeye should keep the same, just change the effect of them (like you did with Winter Soldier).
Special 1 - keeps causing that massive bleeding and draining power.
Special 2 - since there is some shock in this arrow, it should causes shock
Special 3 - many arrows that explode, huh? it should causes incinerate
Don't I need to say that shock and incinerate has to cause a big loss of HP like special 1, otherwise they're not that useful
