I am planning to roll Mistweaver out of the gate. I had planned on Resto Druid, but I am not impressed after patch. I'll be going ham on Windwalker as well. If that class doesn't pan out for Mythic + (not sure why they wouldn't), I can hard switch to something more compatible. Both are looking really strong in BGs though. Mistweaver also has the 2nd highest damage output as a healer (2nd only behind Disc, and actually #1 on AoE pulls), so this should assist with clear speeds. If somebody else ends up swapping a healer from time to time and Windwalker is garbage, I'll most likely have a Boomkin or Fire Mage available.

Im good to commit to two evenings (not Sunday...GoT, Walking Dead, etc.) 9p EDT to 12p-1a EDT works best for me. Pref not two days in a row, but its no biggie is most can only do two back to back.
