Master+ euw role assignment is completely ruined

The update said midlaners would get their role more often and that queue times would be longer in master+. I am a midmain and a master+ player and my experience since the update is an estimated 3:00-4:30 queue which pops at 2 minutes and fills me jungle when my selected role is mid/top. Yes I even get filled jung>bot>top more than top>any other non-selected role. MMR is supposed to be closer together for longer queue times..I got shorter queue times and yes while I do get less D1 players I get more players whos MMR is further from mine on the upside compared to how far from mine a d1's would be. For example I'm at 50lp and instead of getting a 70lp D1 player i'd get a 300lp master player.
