Exactly. Again, Thracia did it with Eyvel (Very interesting in her case), Lifis, Dagdar, Sara, Galzus and Raydrik (He's always around regardless).
Mind you, they didn't do enough with that even then. One can theoretically have Tanya attack Deadlord Dagdar and there was no reaction or anything despite her father becoming a Deadlord.
But I'm rambling. The point stands. I'm glad there's actual monsters, but if they absolutely have to bring back Risen, why not go with that? Sounds lame, but it would show the enemy being a lot more sinister.
