The last twenty 1v1 matches as usf all of my opponents were OKW and lost almost every single one of them. On Kolodny Ferma I had a match where I played perfectly, but still lost because he built a schwerer HQ in de middle of the map in the beginning of the match.
I guarantee you didn't play "perfectly". If I'm wrong, go ahead and win next ESL tournament, free money.
Also, if you look at the recent win ratios you will see that OKW only has a very slight win ratio advantage over other factions in 1v1 matches below rank 500, and USF actually has the highest win rate among more experienced players.

Best option if you're really stuck is, as has already been suggested, to submit replays and take advice from people who aren't having the same problems.
