I had huge issues with the final boss, but I didn't realize I could simply jump out of the debuff or that I could grounding totem the other thing. I only have 1 shaman per team, but every little bit will help. I technically could bring in both my shaman for this fight if I need to, but I would much rather have my the two teams of 5 be independent of one another for 5 mans. My big problem is my tank wasn't really strong enough to last yet. I guess I had no +defense gear anymore with the rewards from quests being pure stam. HOWEVER now I have the 3 blue tank items from doing the other three quests, so I might go back in tonight. Those items give a ton of defense.
