Why?

I'm not one to complain or be on the boards bitching But I need to rant Just played a decently good support game at least by my standards because personally I think I suck but my team just... We still won it didn't ever really go south but I was defiantly a factor in us winning well Every mistake they made was blamed on me then end game screen comes up and I get reported by 3 of them for "Being a bad support" and "Thrash at this game" for all their deaths. Normally it's like sure whatever Idc I played well Got an S- I'm not really upset but I'm so sick of this shit I get the most toxic teammates even the ones trying to calm the situation down are toxic and because of it I got reported by 3 people on my team and 2 on the other. Just WHY????????
