Apparently Bladedancers can damage Crota also (Recruitment)

just a heads up

Not with Arcblade. Being a blade dancer is just beneficial since you can be invisible and not have to worry about him smashing you before his shields are down.

Turn on the perk that makes you invisible when you land a blink strike, increased invisibility duration, and blink strike cooldown reduction. Then you crouch to go invisible, and run up to Crota and stand next to him. You can begin damaging him while he starts crouching. Swipe your sword, and as he gets up drop it, then blink strike to go invisible again, and wait next to him until his shields are down a second time.

Strongly considering asking Korny if I can do this since I'm a hunter.

I'd allow it, but you've got some DPS that we needs. I say Sammy or Guardian does it, since it really does work...
Running it with a group a couple of days ago, and on the first double-drop paired with the death-cheese, Dancey McBlinky had Crota's health down by a third. I dun seen it with my own eye).
