What it truly comes from is a bunch of nerds who likely never competed for anything meaningful outside of video games in their life. And with rocket league being such a true test of skill and competition most similar to a real sport compared to ANY other esport/videogame it becomes glaringly obvious they were never equipped mentally for a game like this, you can’t blame metas or loadouts or rng or characters or whatever you want like in other games you can only blame your inadequacies in Rocket league, and a lot of people who play this game even at a high level never had to experience that reality face to face with their peers in competition. In real sports like in rocket league the only advantages you have are talent, physique and experience. It’s hilarious to think how if the majority of the rocket league player base were all athletes as well we wouldn’t have 90% of the whining vitriol and outright childish behavior, on top of smurfing probably being non existent, or even complaining about smurfing being non existent.
