Overwatch is a lovely place isn’t it?
Never had this scale of a problem before

The rest of my team spawn camped the enemy team on hanamura point B then continued to ignore me when I said come back which resulted in losing the point due to half the enemy team going around my team. Then insisted DVA could hold her own easy against a Lucio, a rein and a Hammond with no healing and also said if I didn’t like it I should leave.
So basically the 5 other players on my team were smurfs (we steamrolled the enemy team very quickly for just bronze players) and throwers because they didn’t seem to acknowledge the fact they left me, a DVA player on the point with no support.
Never seen it like that, ever, never 5 players on own team
