We need 2 separate patches for balancing
One for High elo and one for Low elo. They are 2 very different groupings on how champions proform. What is op for low is also for higher. But what is ok for high is broken for low. Mainly because of team based mechanics being worked into how balanced a champion is. Low elo has less 4-5 man premade teams. While high elo usually has less solo players. So balancing around teamwork for low elo isn't necessarily appropriate. Maybe having 2 separate balancing patches for low and high elo could fix some of these broken champions in low while still keeping the fairness for high elo.
For this low is unranked - gold 1 and high is diamond 5 - LCS. Platnium is a middle ground where you can choose which patch to play on.
