We’re currently at the stage where regular ToC is too easy (we’re clearing it, VoA, and Onyxia in just a couple hours or so), but heroic ToC is a serious pain in the badonkadonk. So the other night we took a night off from serious progression and went back to Ulduar to clear out The Keepers and General Vezax so we could take another shot at Yogg-Saron sometime. We thought it would be a faceroll and so we were a little surprised to find that even after gearing up from multiple clears of ToC, Ulduar is still pleasantly challenging. Hodir was less than forgiving of the fact that everyone except for me (I was tanking him) didn’t bother to bring any frost resist gear this time. Our healers were a little frazzled after we downed him. Thorim was fine after one wipe due to deaths in the arena, but it’s still one of those fights where you might be biting your nails waiting for the corridor group to clear through if you weren’t using your fingers to mash buttons. Freya was fine. She gave us quite a bit of trouble in the past but she was the easiest of The Keepers that evening. Mimiron is, well, still Mimiron. Unless everyone is on their game you can easily find yourself with only half your raid at the last phase. I am looking forward to doing General Vezax again when we get back to raiding again after the holiday. I really enjoy the mechanics of that fight.
My thought after that night is that of all the raid content in Wrath of the Lich King so far, Ulduar is the most interesting, challenging (once you account for gear), and rewarding. Naxxramas and (regular) ToC were/are fun, but at times they feel too much like a heroic 5-man with 5 to 20 extra people. But Ulduar feels like raiding.
