The results are in. As far as off spec dps goes, ret is without a doubt at the bottom of the barrel with shamans coming in a close second. Rets viability is virtually identical to a holy paladin. Choose meager dps with utility or a fully capable healer with utility? Or skip the utility because you have enough holys and bring a real dps to the fight. At least druids, priests, and shamans provide an ancillary buff to others in the raid. If you have enough holys you don't need another aura or blessing.
