Darksage's original post and last one actually gave me an idea. The class perks should be something you build on based off of your merits with the class (be it kills, badges, etc haven't thought it out yet). You'd start with a small perk and the more you play the class the bigger this bonus will be. For example (using your original idea) defenders would start off with, say, +2 bonus damage when near a friendly base. Once fully "leveled" you'd have something like +10 bonus damage when near a friendly base.
