So, every droid a person builds has two steps: build the body, build the brain. If I was building a Mouse Droid Milion Army (okay, an army of 5 we'll say), build a body, increase the minion group by one - that makes sense. But when it comes time to install the brain, in theory for each minion I wind up building (assuming the roll comes out with the right number of advantages), I could install another general skill. Roll enough times, and I'd wind up with bunch of minions with every skill under the sun.
That seems a bit unbalancing.
Or is it when you increase the minion group, would you go with just adding the body and skip the programming step assuming it's just part of a hive mind?
