A couple of things that need to be incorporated to the "master doc":
1. Initiative. I've got a basic idea to let leaders use action points to modify initiative rolls but haven't thought much about it beyond that
2. Opportunity attacks. "saving" some action points to interrupt the other guy while he's acting - maybe require leader/hero intervention?
3. Ability lists. Need to nail these down beyond some general outlines, and then figure out how to expand the spells/powers/tech/gadgets list
