Because there are a lot of YouTube videos out there about Hunters being "weak" in PvE play....which is non-sense. Gunslinger Hunters just take more skill to use. But as the saying goes, "All good judgment is the product of previous POOR judgement". All it will take is a few attempts at strikes and raids with badly unbalanced fireteams for people to realize that a good offense....is the best defense. Hunters are reliable, DURABLE dps characters....and Bladedancer probably has the strongest AOE attack in the game. So anyone who decides to *categorically* leave them out of end-game missions is being foolish, short-sighted...and will probably (not) live to regret being so.
