Funny, but I've been toying with the idea of speccing my Shaman resto and my priest shadow when the hit 70 and my crew is a fivesome. As long as the shaman can heal my paladin, it seems that the shadow priest boosting my warlock would lead to higher DPS. Any thoughts with my crew? (mage/lock for DPS, pally tank with either shaman/priest as healer/DPS or the reverse)
