I have been top 500 in OW1 so dunno, define what you consider “suck at it” for me?
A rigged game is not always the same as an impossible game either, thou it is a matter if you like the experience or not. Clearly a lot of people do not. No other game even comes close to the amount of complaints on the matchmaker. Closest is something like LoL and that game has countless more players.
