For most of the 3rd and 4th seasons, I sat just bellow Silver (900 - 1300 SR). Of course I think I should be higher, but that's a fair place for me to be, and I enjoy playing at that level.
Over the last few nights I had a very long loss streak and am now around 700 SR. At this level I've had multiple games where Mercys refuse to heal and just shoot, you can win a game with 6 attack heros, and people are so toxic that I often remove myself from voice chat. I play tanks and healers, and so I enjoy the game most when my team is playing together. Right now, my enjoyment of the game is shot.
I'm worried that I now have a terribly low MMR and will continue to place at this level next season.
Question: Given the way the SR / MMR system works, what things can I do to increase my chances of placing higher next season?
Like, for example, would it help if I stuck to Quick Play for a while to up my MMR before doing the Season 5 Qualifying Matches? Should I create a new account to get a clean MMR?
I'm aware that long term, I should probably go to Looking-For-Group sites and find a community, but at the moment "700 SR healer/tank" won't get any clicks.
Note that I am not looking for gameplay tips, I'm specifically asking about "resetting" my SR / MMR.
