Well the fuck up of riot was massive somehow that needs to get fixed. I personally pledge for a hard reset for years now (especially because of the damage done by dynamic queue) but riot will never do this.
Instead it will take weeks if not months for all the self boosted players to drop back. It's insane that five seasons plat players are now in masters and grandmasters with negative winrates hardcore flaming actual (multiple) challenger players. Every noway stream i watch is a shitfest then i look up op.gg and half of the matches players were plat/low dia the seasons before.
It also sucks for the better players of course, naturally when you reach your skillpoint you flat out your winrate but you have always had to maintain a 55% winrate you keep your rank in masters+. All the bad/boosted players will be flushed out of grandmasters and probably masters pretty quickly but diamond (as always) will keep being a shitfest of frustrated diamonds who get fucked by riot the most because they are not good enough for masters/grandmasters and now get punished even harder because of the LP gains while it will take months to years for the formerly boosted players to drop back because you don't have to play to keep your ranked in diamond. I think diamond would be much better off if you had to keep playing consistently against decay like you have in masters+. As it is now it will ruin diamond for months probably years. But riot doesn't care as long as it is not high elo/pro level or super low elo.
