What mixed hero class of the (Necropolis) faction do you like?

By the way, I rarely play as the Necropolis faction... very rarely. But I often use Death Magic for my favorite archmage. As for the Death Knight (with Tactics), what do you think would be the best skills to develop for him?

P.S. AndersonAD, I understand everything... your moderation service is like that. But be more lenient. There are so few people on this thread anyway, and the last ones might leave. People are having an interesting conversation. Let them deviate from the topic a little... At least it will boost the thread's rating.
Just saying. A tactical approach :) I just want the Heroes 4 thread to thrive.
