Also--since you're messing around with the30% rule.
Can you add in more than a vague binary response? I'd like to actually see the % i have, so I can tell if i am barely over the limit, or if i can add another heavy/cav/etc. Right now the guess and check is rather annoying/time consuming.
And don't do the coop using command points thing... don't do it.
If people want to sit around and play continuously all day... well, be glad people like your game so much.
