..and LOVED IT.
Made very epic by a few factors:
Offspec tank and healer
Random mechanics we didn't know about until 3 hours in
Buggy boss mechanics (lava puddle graphic disappearing)
Slightly delirious due to the lack of sleep around cata launch (realising I was the only person in group who's name didn't start with "G" was hilarious apparently)
Whole group only just geared enough to enter random heroics
Lots of fun chat on vent the whole time
I don't care if you 1-shot it, I loved the feeling of accomplishment I got when we finally downed it. Moar plix!
