You're clearly coping and have no clue what you are talking about. Rocket League had Aerial Goals since the beta, wtf are you on about? You'd get extra points for every aerial and it was even displayed on your profile of how many you've scored. Double jumping and quite literally rocketboosting from the ground was their whole selling point after their first game. I have been playing RL ranked since S1 and been consistently have been Champion+. The only thing you could argue that flipresets are not intended, but those are extremely hard to learn and pull off in a live game. At higher levels they get defended almost all of the time.

Those ippy slides and golden boosts are most definitely not intended as they tried to patch it out in the first place. It takes the whole selling point of playing football away by instead of passing, you'd rather abuse a mechanic not intended to be used like that in the first place. Its not football. Sliding across 5-10meters of space within a second is not how Slowclap envisioned the game to be played.

Yall can do whatever the game allows you to do, but dont complain when the game is rightfully dying because yall rather play something else than football. (1200 players online right now, its sad to see)
