adv adv marauders doesnt sound too good. All alien species (excluding dretches and tyrants, unless you play tremX) have 2 sub-classes, adv and normal, making a 3rd sub-class would ruin it and we'd have to make 3 sub-classes for every other species, imagine adv adv goons. The only way this'd happen is if S4 was coded into Tremulous, which isn't going to happen.
