Exactly.. but let me explain, the whole idea of starcraft is to suprise/counter your opponent, and kill him after he makes a mistake.

If your actually good, and you take away the counter/suprise factor, you will NOT lose, EVER, not to the best person in the world, if your pro level, borderline even, you could beat anyone with it.

If you see an expo and an opening, and you waste 400 of their minerals, boom, upper hand, if you waste thei rnatural, boom you win.
