Thinking about creating a new 4e Shadow Leader / Controller class that specialises in creating and summoning undead servants. At this moment in time, I am thinking of going down a more 3.5 route, so that the added creatures would have their own initiative's and actions, which may worry some. However, in my (not inconsiderable ;p ) experience "adds" can speed rather than slow combat as they give the group extra firepower, which defeats foes more quickly.
I do appreciate however that others may not agree with me, and so may hate the idea. Each to their own I guess.
Anyway, I'll post the class as I create it, and would appreciate all feedback, good and bad... Though helpful only (pretty please).
