Social LoL

So I was playing TFT yesterday. I played 11 games, everyone was silent in those games. Then I played Destiny 2, everyone was silent in those games too. Then I played one ARAM game. The enemy team was winning and two or three of them spammed their masteries, and the panth said ez, Our Ekko rage quit and it was 4vs5. It was pretty cringe player behavior, especially since they weren't even good. I mean, all the Panth did was spam e and q. The Talon abused snowball and ult to take no damage because we had no cc. The Blitzcrank just qd and ran away, being able to spam q and eventually hit one because we had no engage. They all abused flash because it has a lower cd in ARAM. Ezreal spammed R. I mean, do you feel that good about yourself just by doing well in an ARAM where the enemy team has no counters? How did the players become like this? o-o
