WoW raiding is a bit strange these days, because this kill is actually just the beginning of the road. Now we get to watch the hard modes, which is likely to take quite a bit longer. That's our hope, at least. Will Ensidia walk away with hard mode Lich King as well, or will a group of underdogs come from behind? Will Stars show up in the spotlight again? Only time will tell.
Update: Ensidia's raiders have received a 72-hour ban from the game for "abuse of in-game mechanics or glitches with intent to exploit or cheat in World of Warcraft." A hotfix was applied last night to prevent the use of Saronite Bombs (which Ensidia used) in the encounter and Ensidia's loot and achievements have been removed. So that world first? Still up for grabs.
