Player Level Battles

#1

Have not seen it mentioned but think we need some kind of balancing so players are attacking players close to their own level.  Have a friend who is level 95 being constantly attacked by level 120+ players for easy gold.  Can a system be developed whereby you can only attack someone withing a range of your own level?  For example, since my friend is level 95 only people in the range of say 90 to 100 can attack him or something similar?

Its part of the game…protect your gold or empty your safe…those players will move on
