I don't, it was always like this cr*p.
That's why Wolves' Den gave me cancer.
I was having nice wonderful fights till gold promo, then I got the same unranked healer 3 times in row and lost it.
Last season 1260 > 800+-, because of wonderful matchmaking too.
I will rather wait 1 hour for balanced match than lose in 2 minutes and then be salty for the rest of the day.
I know that you are a healer, but I personally can deal with unbalanced fellow melee DPS and a tank but if there is inbalance between healers it is kinda RIP.
