I'd be ok with that as long as the super wast wasted if you got nothing accomplished. if a titan tries to run in to use his super and dies he gets his super back (chances are he died before activating). if a warlock does the same thing. but a hunter needs to activate his super and then try to run in due to the long activation time, during witch there is enough time to easily kill the hunter, and then try to get into range, where they can be fairly easily killed before even getting into range.
