I was halfway through a 4 necro 1 priest game when my computer monitor died, and when it came back from a long vacation in Germany, I had forgotten enough about the game to want to resume it, and I also wanted to play my favourites first 
What I do remember is that it was a very nice game, and the advantages of having a lot of magic more than made up for the irritation of having to swap characters. So far I have agreed with your opinion that it is not a good thing to swap party members, but I'm slowly changing my opinion about it. I suspect that at the end of the game I would have to swap in a vampire somewhere. A memory appears about armageddon in the plane between planes
