I think they should make sprint and evade buttons but change them a little bit to fix some of the problems with having both at the same time.
I hate when people run away or use double beat down, so I thought that we could make sprint so you could use it when there was no enemies on your radar. But when you where alone you could sprint forever.
And evade so you could tap to short times and evade half of what you does in reach, or you could hold it for a short time and jump really far like in reach, but then you only could do it one time before recharge.
The recharge should obvious be longer if we changed it like this.
