Seeing as blade dancing only averages 1 more kill than all the other supers I say it's fine. I'm a hunter however every time I use blade dancer and get 3 kills with it, at least two of them are close enough to each other to be killed with a nova bomb or FoH. Whenever I get 4 or 5 kills with blade dancer, there team is close enough for 3-4 of them to killed with the other classes super. However that's if you don't die as a blade dancer and that's also considering you don't panic kill with the other supers. I also play warlock, and honestly never panic super, it's really a waste.
