There's always the inherent fear of on-kill bonuses and reset comps becoming too snowbally, and that might happen here with Cass's on-kill heal (she could either be too far ahead to ever be killed before she kills a target and resets, or she could be too far behind to heal before dying), but that would also boil down more to balancing. It would definitely be very good against, though.
