What I'm wondering is: if anyone can suggest a strategy to keep the game from going to a state where it's less about building an overwhelming force?

After watching some VODs online I've noticed that army sizes increase as the game progresses. Which makes sense, because as the economy of each player increases they are able to produce more and more units, and build more and more structures (or have built more structures).

I think I see smaller Armies in the Pro games (anybody agree with that?). (Yes, eventually one force gains enough of a lead to make the large, overwhelming army -- and it usually is near the end of the game).
