Play Rock, Paper, Scissors. Do you want a complex game with 100+ character choices and many different items to make them all have varying build paths? Play league. Things wont ever be 100% balanced and that's the nature of the game. Ebb and flow of power rise and fall across champs and items. Put down the salt.
