Normal games behaviour

I mean, i have some toxic ranked games, but normal games, it's like, they all gather there and flame each other:))..every game.I played a game and me( support) and my adc we had diamond borders. Anyway, my adc wasn;t doing too hot and everybody flamed him.. boosted, sell skin etc. The guy was low plat in this season. But the flame lol..they didn;t shut up all game long:)).My mmr for normal games it's around gold level. If this is how your games are, holy shit man:))..every game it;s a challenge:)))
