I tanked Uldaman in a PUG last night. I don't think I ever went through it back in the day. That place is a pain in the dick, especially with a shitty, cranky pug.
It may be that I'm just a shitty tank but I find it hard as hell to maintain any sort of aggro when you're dealing with multiple mobs. Charge, switch stance, taunt, tab, sunder, sunder, tab, sunder. This shit takes time. Meanwhile every dps in the group is trying to grow the biggest epeen by AoEing and/or single targeting any mob they feel like regardless of which one is marked with the skull.
Also, not a single fucking piece of plate in the whole god damned instance, green or blue.
