i too overflow in battledroids. i just use em as minifigs, but throw in robot cliches, like the inability to show fear, incapability of love, and they bleed highly flammable gasoline.
basically, what this means to you: lots of different species and classes don't need seperate stats. instead of thinking "what are robots better and worse at?", think "What would a robot do here?". and then push their grandmas down some stairs.
