I have a +50% threat gen stance. Only time I needed to taunt was when Gwy leaped ahead of me. (Granted, being way ahead in levels also made it easy.)
Avi, I think, said that nothing ever peeled off of me onto her, so at least healing-wise, that was fine. So as long as you're not flinging around AOE on the pull, I think it should be fine. Or if it's Normals, then pfft, whatever.
