Oooook. I'm not really going to try and respond to everything that got posted over the weekend (which, as you may have noticed, I'm usually not around for).
I'm going to wait a little and let you lot sort out who's in what group before commenting in depth on builds and the like. I've replied to PMs and such from the weekend, and if I missed needed rulings, just trout me with them and I'll respond.
Also, as a warning, I'll be on vacation from the 15th to the 19th of Oct.
To the regional benefits, I'm going to make those up after the builds are chosen, for two reasons: so no one picks a build based on one, and so I don't royally screw anyone either.
