Take a break with making new champs and just fix all champs.

Right now League is currently in a weird state. Where there is a few really OP champs and then a sea of champs that aren't even needed now because of the OP champs. Maybe instead of making new champions Riot needs to focus a lot of effort on the balance of the game. Because it isn't where it should be. I think having the game come closer to where it needs to be in balance terms will keep the old players still playing. And once that is in a better spot than Champion creation can resume. Because now it just seems that new champions instantly come out OP. Maybe try adding them in really underpowered and then buffing them until they are in a good spot.

Side note Riot. Doing a rework on a newer champion isn't always such a bad idea. You can redo their kits in order to make them play a bit more fairly. Champion identity is what you make the champion. Just because they don't have an old move doesn't mean you're destroying the champion.
