I thought this would be a good place (vs questions and answers) to discuss the new chat game.
@umi, I can email you some maptools stuff if you want to play around with those sort of things and get familiar before saturday.
I agree, role balance isn't essential in my eye. Roles are nice to have, but never required. Also, I am under the impression, umi would tailor encounters so a group full of tiefling sorcerers wouldn't die.
I think I have decided on a dragonborn warden (Minos) for my "quest" character, and a deva avenger (Dax) for my "mission" character.
