I'm currently playing with Sandor, the Blood Warrior, but I'm not really having any major problems.
Right now, I'm about to start the third mission with him, and I'll specifically set the difficulty to Hard to see what's so scary there.
By the way, I played through Cove with the Sorceress, because when the guys run away, I'm too lazy to chase them down and attack – I just let them go in peace).

That's a great idea! I don't really use these spells much anyway – I'll focus on blood magic!
