Re: Favourite Instance or raid...
Of the 5-mans my favorites were Stratholme, Old Hillsbrad, The Black Morass, Blood Furnace (love the way it looks), and Dire Maul North. For raids, Blackwing Lair and Naxxramas. They haven't recaptured the spirit of raiding pre-BC, hopefully that will change after the next expansion. Never got into the new raid zones.
