Just to throw another monkey-wrench into the discussion...

I just realized there's a lvl 42 Shadow Priest on the Hunter's account. (too many scattered midlevel random toons to count rofl. Bad case of alt-itis)

S-Priest has fine dps/utility. Easy enough to castsequence his dps with a Mage I'm sure... is 2 priests overkill though, even if one is offensive?
