Managing 30 is hard enough. Logic in it I'm guessing is that it's to keep the game going and interactive. Adults who play that has real life things to juggle. I invest and look forward to sales. Need x amount and level. That is just too much. Please take this into consideration. Also when I expanded I can't just expand to this x size need to expand prior size before that?! That's a bit "whack" if I'm right in my assessment.
