Attacks decided by level, and not trophy count
I think attacks would be improved by only being allowed to attack someone within +\- 5 levels of yourself. For example if I were a level 50 the only people I could attack would be between levels 45 and 55. This would require people to use skill when attacking as opposed to just dropping trophies and attacking somebody who is way too easy. Nobody a low level can defend themselves when being attacked by someone twice their level. Anyway, just my 2 cents worth.
