"Crashing the economy" - why is this bad?
I've seen this "don't crash your economy" advice many times, but don't understand it. Does my overall build rate suffer if metal or rad production goes negative? Meaning, is there a penalty on this? Or are the indicators simply telling me that I'm trying to use more resources than I'm harvesting so production will be slower than "normal"?
I think it's the latter case, meaning it's actually desirable to be negative because then no resources are being wasted. But if so, why all the advice against getting into this condition?
In any case, I can't track and predict things well enough to stay in the positive resource band... I'm always building frantically to fend off the AI. The only time I have both resources positive is when I'm finally advancing on the enemy Nexus.
