I know, but I like Skirmish games that last hours. I like turtling and having a chokepoint in the middle of the map where I can keep the enemy at bay and make my base look are pretty. The cap annoys me as once you have enough sectors to get a decent force you easily win anyway.
Might not be the game for you then. I think CoH is up there as my favourite RTS ever because it forced me to break my habit of turtling. You really have to be aggressive and try and acquire points - the unit cap prevents turtling until you have 50 tanks and just rolling them into the enemies base.
