why does it take boosted d5's so long to get demoted?

such a flaw. 46% win rate kids feeding and are both on 5 game losing sprees at 0 lp. Meanwhile their team gets a 3 man that has an 80% win rate together great shit! Like seriously if you ever at all think this season matters at all it doesn't one bit. Dynamic que has literally fucking broken the game. If you have any doubts go look at my match history. I either destroy the enemy or I get 1-2 boosted players that are beyond useless.
