Group with lvl65-68 wanted to raid this one. Warrior 105/T3 Groupgeared came for help. Expected that the healers had perhaps a bit to do. But the 6,5k damage didnt even came through, the most time this mob missed, to my surprise. So if you want to have a bit more fever in this fight, don't take something 95+, then the whole raid does not feel like a walk in the sunshine here. Even the casters had no problem to go into melee.
Perhaps a short note:
1. Tunat stays in the middle of the room. Beat him down to Zero.
2. Tunat appears behind the platform in the back of the room. Beat him down again. Then he starts to change all forms of all raid mobs in the zone step by step. The typical features of the raid mobs are there but only to a very small degree (e.g. 2x adds in the form of ZunMuram Mordl Delt, the original had about 12 adds during the fight).
After that it is loot time.
He has a DS always present but its relatively weak.
