Slow Down Champion Creation
This game already has a ton of champions. You guys should really slow down the process of creating new champions. Focus on balancing the stuff that needs balancing first. Constantly adding new champions only delays that process by so much longer. When a new champion becomes op or meta, it changes the things that people play and in turn what you guys balance around. If you guys really want to balance the game for a majority of champions, you'll slow down the process of creating champions.
