At the beginning of the game I've decided it's important to spread out thinly, avoid enemy contact, and claim as many resource points as possible. Yes?
But then it's less clear to me when is the best time to engage the enemy?
If I counter attack as soon as they start taking my resources I seem to get drawn into endless unit production and make inadequate progress on infrastructure;
But if I leave them to it, and I build, then I find myself unable to replenish my resources quickly enough to build those superior units.
Any tips on how to balance these two extremes? What events might signal to me that it's time to swap my focus?
