I say he should have a slow health regen, and he has a special that allows him to fire an arrow, which will leach health from his target to him, like in hordes.io.

It could be like in Overwatch, with Hanzo. His special is a bow that shoots 3 arrows or an arrow that tells you someone is in the area. So it could be like a hidden mine, and when someone steps on it, they blow up.

Could you change the hotkey for triggering the dash? I find that I accidentally trigger it and/or dash in a different direction I want.
