Why are promo series even at all tied to MMR
Just an aside from that other thread about the LP system/
Entire reason I stopped giving a crap about ranking up and just rushed gold 5 this season, because last season (or maybe it was season before last, I forget long time ago with little fucks given) I was put against diamond players just trying to promote between divisions in plat.
To advance to a rank you should be against players at or slightly above that rank, not whatever the hell your MMR is at the time.
