If you made Onslaught identical to the existing gap closers, it would be a straight up nerf to WAR. That's fine if you want it.

But the idea of keeping Onslaught the way it is now, while removing the gauge cost, is simply unreasonable. There are two tank jobs at the moment which have serious problems, and WAR players are complaining that a trifling issue like this isn't skewed enough in WAR's favour. Quite frankly, I think it's disgusting.
