good questions
i can only guess, but I'm almost sure that it will be like low droids weak, higher "classes" very powerful vs human players, but the humans will most likely have an easier job when they attack the enemy base
humans might have to stick together to provide each other with coverfire against droid stealthattacks and droids might have to stick together to have a chance against human base defense
but I cant really say, because i only cared about proposals for the look of the mod so far...
