Uh-huh. Considering how much you've complained about having to move out of range to get the Momentum buff, I don't buy it. And it's not like Hunters haven't been dealing with that since... whenever Disengage was first introduced.
Having said that, I actually don't mind the idea of using another ability like Fel Rush to get out of it, but just animation canceling it with a jump/glide? That's garbage.
