Literal trio group on tank and both supports blame everyone else when they literally could not synergize one bit. Also we lost the last fight with both their ults up way before they died. God damn OW2 is trash in comparison to classic. TankSupportwatch is garbage. Make all roles equal so you can actually carry games and not rely on your tank and supports doing the most basic.
Sounds like a player problem. If you let donkeys play, you will get donkey matches. Nothing the game, match making, or anything like that can do.
