I don't know if it is a new, fresh idea or somebody already thought of that. It SHOULD be a RULE in Monster Legends Arena fights and Team Wars- AGAINST attacking monsters more than (let's say) 10 levels weaker than attacker's levels.
Buffed up monsters against EQUALLY BUFFED monsters! Now, that would bring forth SKILLFULL players.
Ok, you need money of those kids who buy monsters on "12000th" level and brag they are the best monster masters.
Edit: I moved this thread from Dragon City to Monster Legend section. I think that is where you wanted to put it.
