please consider the new ranking system
The new ranking system was designed to let players to have 5 separate rank for 5 position. However, if someone focus on one position, he may not care about the lp on other position. The result is, he doesn't pay full attention when he got autofilled. Also, in higher rank like diamond, master and challenger, not everyone can be placed in the position they want, they often negotiate to swap, so not everyone can get lp for the position they main. So I think we should bring back the old ranking system.
