You mentioned no Cataclysm Dungeon that run great :c So here is my impression I got.
Most Cata Dungeon need to be babysitted 'cause Blizzard wants it.
The Stonecore & Blackrock Caverns are the only two that run realy great without any attention needed, until now. Most of the other Cata Dungeon need some help at least once, Lost City of Tol'vir runs fine until jumping to Siamat, Grim Bartil fine till you have to mount the Dragons, Throne of the Tides until the elevator, Halls of Origination some Probs with Anhuur + teleporter/elevator and Vortex Pinnacle obviously can't use the Tornados to switch platforms.
So if you have an eye for your IB from time to time, most things will just be fine.
