Banshees... hmm, only useful during sieges (in defense) and even then, only when there are relatively many of them. Vampires - no comments. Zombies - same as with vampires... Skeletons - actually quite amusing... if it weren't for that terrible attack rating... but as it is, there are too few of them (in my opinion). Dragons - I don't know, I never use them. Liches - but these ones I really like, I take them in combination with the second-tier liches, and everything works great. P.S. and here, that attack rating is actually quite useful.
