That brings up another question. Since one base can only support 4 building structures.
Here's the scenario:
You have 2 bases and 8 warpgates. However, due to your crap macro, you have horded 1000 minerals. Do I make warpgates even though I know that I can't support it? What do I do?

I also tend to have the problem of the imbalance of minerals and gas. Sometimes I would have too much minerals and no gas and sometimes vice-versa.
