Ended up swapping talents on the shaman from 22/29 (imp WF totems) to fuill on resto HW/LHW spec. Seems better for single target healing, but DPS did drop by quite a lot. Going to focus on 5/8 and 8/8 on Tier 1 in the coming weeks on the Resto Shaman.

22/29 seems to be good for Rend runs, and Live strat due to the AOE packs and needing to burst them down fast. Was able to clear DM:N comfortably with a proper resto spec.

Other considerations are getting TuF on all warriors to help CC. Maybe even multiple earthshakers for AOE stuns.
