One thing that has always bothered me with ACTA is the stacking limitation. I make models and I often have to use larger bases for the ships than they're supposed to have just for balance and stability. Further, we tend to have big fur-ball games.
Remembering that this is a space game and only the center of the stand counts usually, there's got to be a mechanism to allow ships to stack fairly. In my home games we just allow it now - chits over each other, 6 fighter flights 2" on any given ship at any one time and in the case of miniatures, place as close to where it belongs as possible. It's a gentleman's game. Nevertheless, I think such things should be official. Consider adopting such things in 2e.
