I played this game for a month and when I attack an enemy base destroying me completely. I'm simple, but in enemy bases too difficult. He grinds the machinery, heavy giant air units, has completed upgrades, infinite resources, and my strength in the hundreds, but never to destroy enemy bases. What am I doing wrong? Any tips?
