When I first got battle revolution I was a noob and didn't know a thing about compedetive battling. As you can guess, I got owned on wifi. Anyway, now I am much better and have a good team with some EV trained pokes (I'm was to exited to use my dragonite and went on wifi before my team was done) and I seem to be facing harder opponents. At first I fought many uber noobs, which I pwned, but now I'm getting some real enemies. The only 2 reasons I can think of are: Uber noobs are stopping playing PBR (I wish...) and, there is a hidden ranking system built in on wifi. People who have higher ranks play eachother. It explains why after you beat a few uber noobs, you stop seeing them. It also explains why people would disconnect, other then just being retards.
