1.) No, just no. We don't want to make it completely useless damage wise and healing enemies would be counter productive
2.) EDIT: Nevermind this isn't actually possible: I think making swing speed the same across the board for all classes would be the first good step. Right now having it as a heavy swings slower than a scout, maybe if we bring them all in line by either slowing them down or speeding them up.
3.) We can't change this.
4.) I don't think we can do that. The way it works right now is that it has the knockback attribute, but it is set to a negative value. I don't know how we would force people upwards with it.
5.) People are complaining about the fire rate though, this would only make things work I think
