Skilled, mixed, smart and equipped high level (with respect to my party) enemy parties. Perhaps it is because my appreciation for tactical combat challenges is so high, but i always find Mencar, Tanor, Koshi, Samia, Drizzt, Shangalar and their respective comrades to be the most enjoyable non-weimer battles in the game.
BG2 is really a great hybrid between a CRPG and a tactical simulator... But i'll save that for an other topic.
