The reason my level kept going up when I was out of town this weekend is because I was attacking CHINGON over and over (he has been offline for 22 days and is a level 80). I get 20-30% experience every time I attack him. The hotel I was in had internet, I just didn't have very much time to play.

I had sold NA, and sent Click all of my money to gain interest while I was gone because my playing time was so infrequent. Therefore, I was unable to train at the gym, so all I did was attack CHINGON. I probably attacked him 15 times or so.
