Unnecessary. Then or now. Because it all leads to stuff like this:
"What about an ability to use knuckle clusters or his ult as a "grenade jump"? I think he could use some movement."
Suddenly every single legend needs, DESERVES, to take less damage while dealing more, while healing faster, while moving like a mobility legend. Carry this thinking to it's logical conclusion and suddenly every single legend in the game can do EVERYTHING, do it FASTER, and then the game is nothing more than a coked up cluster **bleep** taking place in a fog of smoke and grenades. Where is it all supposed to stop?
