Smurfing is a big problem in league.
There are two types of smurfing. One is creating a new account and then ranking it up. This one is fine and does not do a lot of harm. The other one is purposefully losing a lot of matches so that you can reach bronze. And then rank up and smash new players. Some players who have reached plat and diamond, will have a win rate of <40%. The usually achieve this by playing wrong champs in the wrong role. For example jg janna, vayne jg etc. They achieve such low winrate by purposefully losing games. This needs to be fixed. A plat player has no buisenss in bronze or silver. This is just abusing the damn system
