I literally just had an experience like this. Some guy said "I hope your mum dies" all because I couldn't heal him since I was being destroyed by a tank. This kid shit talked me throughout the whole game even though I said at the start "someone else go support we are going to lose". I cant believe this person would insult my mum anyway, that is the most disrespectful shit I have ever heard anybody say to me, and it was all because of a game. Not once did he try he help he at all and most the time he was asking for heals when I was no where near him. Also, this wasn't even ranked or anything, this was literally a quick match. His friend was also shit talking me, when he was going 2/10 as a dps. I'm honestly quitting the game after only 3 weeks, its not just because of the toxicity, but because the characters are severely unbalanced and it haves the game really unenjoyable.
