Yes! Yes! Best part of the game! More uppity wannabees to slay! RAAAGGH!Give us more arrogant warparties to destroy!
I also liked the fight with the Demon Knight on the bottom of Durlag's Tower. Spent 10 minutes preparing (drinking potions, casting prep spells) and he dispells all of that the moment I charge him!
Most of the Mage battles were also fun, as were all the assassins, the Wyvern cave, and that big guy in the Bandit Camp.
