Well my question was mostly theoretical, my buddies who I mainly play with have been pretty busy lately and we haven't played in quite a while, so I'm going to introduce some new friends to the hobby, but thats got to wait until I can get my 3d recreations of the siege of the citidel boards finished and paint up enough of 3 more factions to add to my Imperials, since thats all I've got painted at this point.
The target audience are new to miniature wargaming but are all roleplayers with a good head for rule systems. After a quick once over of the SA section I think Ambush, Camouflage, Channel (Maybe?), Climb, Deadshot, Demo Training, Enhanced Charge, Fast Shot, Medic, Natural Attack, Necromancy, Necrorganic resistance, and Zombie master don't specifically need to be avoided, though I wouldn't have more than 1 present in any single army with the obvious exception of Necrorganic Resitance and Zombie master, that way there are some neat abilities but no one has too much to learn.
I think I'm going to use Capitol, Imperial, Crecentia, and Brotherhood, but its still a long way out and I have plenty of time to think about it.
