Reading the dungeon journal for Oondasta I was uneasy, in thinking how can such a boss be beaten. His abilities look surely like a mandatory wipe. And now Blizzard answered:
So....yes, Oondasta is meant to wipe a Raid, where the second raid,taking advantage of the faction tag should assume the fight, while the first raid recompose itself, preparing to take on the wipe of their pairs.Originally Posted by Blizzard Entertainment
I wonder how low pop realms will work. And I don't dare to think how PvP will do it.
