As somebody who mains a hunter in crucible I can tell you countering a blade dancer is piss easy, if your getting destroyed by them there's something wrong (and im not saying you are, this is just in general). Im typically afraid to use my super because every titan/warlock will just throw a panic counter because they're worried I'm so OP i'll break the game, which strictly isn't true, I'd much rather use my three little words, its more reliable than my super, I only use bladedancer for the invisibility perks which are useful for flanking.
