No champ is OP, system rewards too much gold/xp = snowball
It's not that champion X is op, it's that when you lose a battle in your lane with that champ the other champ get's like 500g/a ton of xp which encourages to snowball, and theres nothing you can do, if you can reduce the rewards for kills by 90%, people can have a legitimate way to comeback from a lost lane.
Problems:
- too much rewards put the other players severely behind.
Solution:
- Reduce the amount of xp/gold by like 80% so that champion X does not get fed when they get a couple of kills.
