You realize how ridiculous it is to play 120 1v1s as one faction and announce that you've come to the convenient conclusion that "my infantry require more skill" right?
I watched this and there was no evidence that would point towards a map hack imo. His artillery targets seemed sensible every time. It looks like one was lucky into the fog of war but it was on the main road, into a high traffic intersection.
This was a good game I was horrified that you lost control of it!
