You are completely correct to attack those higher level than you. However, those higher level than me have been playing the game much longer than me and are logarithmically more difficult to defeat.
For me, attacking is all about the pattern. Train, fight, fight and repeat. This is slightly modified each level, but generally works. If I spent hundreds of dollars to donate and get a nice house, I could win. For me, and most of us at the top of the stats chart, your stats are more important than level (assuming equal equipment). If someone spent time only attacking and never training, that person would be the perfect fodder for any of us. They would be weak, but give good exp.
