1 Diamond + 4 silvers CANNOT win against 5 Platinums and this is UNFAIR matchmaking #Flex q
Games in this queue are almost unwinnable for higher elo players as the game will compensate for this by putting 4 miserable (not literally) players on your team while matching you against a team of about equally skilled players, who are slightly worse than you are but infinitely better than the 4 players on your team. A single player can not offset 4 players being outclassed heavily, the games feel awful to play. Now with many players switching to solo forever the matchmaking will be even worse so the only way this queue can continue to exist is in my opinion by making it the ranked 5 queue again.
