Mixed MMR after roll back of position rank

Reach diamond 4 in ADC on my main. Have gold 1 plat 4 in other role (got demoted to plat during pre-season)

And i get fucking 10LP per win after rollback????? Till yesterday i was getting 19lp perwin????

You just fucked up all the players who acheived higer role in their main role than their non-main

This would not even happend if you didnt introduced position rank.

Please FIX MMR or just reset everyone's rank. WTF

Why you have to mix other role together when you have just deleted non-main role only instead? Why combind?

Just fuck you riot. Fuck you too sapmagic
