Perhaps not OP in the general term, but they do have a HIGHLY advantageous super that can be used without skill, and under a skilled player I can see why this would be popularly flagged as OP. Yes, the hunter may be "squishy", but this is not the same concept it is in RPGs in regards to warriors and wizards. The difference is there, but in crucible it is NOT a major difference between 1 shotting a hunter over a warlock or titan. And the super takes MAJOR advantage of ANY kind of lag. I have seen numberous matches where a bladedancer running around shanking people, and lagging, decimated an entire map, and while everyone playing visibly saw the hunter take rockets, melee hits, etc., never once lost shield, much less came close to dying. Likewise, unless you have a good distance between you and the bladedancer and have time and range to get off a high dmg headshot (which is nigh impossible) the auto-targeting super will win out. I firmly believe this super should not be an auto-target you can button mash in terms of balance, however, this is strictly opinionated from my viewing of the game.
