I've always enjoyed stance dancing, but I would be willing to sacrifice it if it meant more people were comfortable throwing in damage when they felt like it. I know quite a few players who self-admittedly can't handle the stance dancing but wish they could and throw out some DPS here and there without it.

I think the better question to ask is if stance dancing is the only thing keeping healers engaging for a number of players then maybe there's a deeper design problem.
