I know I'm not in the run, but I like to think I've kept up on the theory-crafting for group make-up, at least for DPS. Pre-BC, the hierarchy for melee buffing was battle-shout, totems, TSA and LotP, and battleshout, TSA, totems, LotP for hunter dps. I don't know how to ranke LotP anymore with the healing proc, though it should be more effective than TSA at least, but I know that shamans have moved up to the warrior slot for melee dps, and possible for hunter dps as well. In a sustained dps encounter, and even more in interrupted dps encounter, an enhancement shaman's Unleashed Rage ability, combined with their totems, pushes past Battleshout. Strategic use of commanding shout might still keep a warrior over a shaman, but it's not really possible to quantify and model its effect on DPS output, it's too variable.
