Well so far we have the original and two expansions. Which in your opinion is the best raid so far in the game?
Consider layout, bosses etc. and also consider it playing at the level it was intended for (so doing AQ in lvl 60 gear and not 80).
My all-time favorite is Karazhan, loved the atmosphere, lay-out, and the great boss encounters.
So share with us which your favorite is. (Not the one you dislike or anything, just the one you like most).
