Diamond 5 | -30 lp ~ / +13 lp ~ | 65% winchance ~

Riot didint fixe that? Played this game a long time ago, was Diamond since it exists, account got hacked. Now i start to play this game again in Ranked, and out of a sudden in Diamond 5 i get this lp gains.

Puts me on massive tilt when i see the amount of boosted and bad ppl there and that i need to achieve an 80% winratio to actually climb.

Why is that?
