Blizzard has been bringing their A-game in Icecrown Citadel, with each new wing's difficulty greater than the last. The most recently released wing, The Crimson Halls, plays host to a quartet of vampiric elves who will push your raid to the limit. ICC has been gradually becoming less and less PUG friendly, with complex fights, tight DPS checks via innovative berserk timers, and about twenty different ways to die per encounter. Add in the fact that each end-wing boss has a limited number of attempts, and it's easy to see why raid leaders only want to bring the best of the best to their runs.
The two boss battles we find in the Crimson Halls are night and day when it comes to how a rogue should approach them. The first, an unconventional 'council fight', will have your thief senses tingling as danger comes from every angle while you move about the room. The second, a DPS race of highest order, will have you drooling over the huge numbers that appear on your screen as you assassinate yet another member of royalty: the Queen of the San'layn?
