Yeah, Anubis gets it.
Honestly Sensei, I feel like I have an ability you don't.
I can master almost anything I am interested in faster than most people can when I put my mind to it, this is simply because i'm fiercly competitive and ridiculously curious/addicted to things I enjoy, utterly fascinated!
I've played games religiously since I was a toddler, i've spent most of my life playing games and have VERY good understanding of how to adapt to any gaming enviroment/physics engine.
The controls for Rocket League are simple, and also similar to other games i've played, it's not rocket science, it's easy, all it takes is passion and practise, creativity and good reactions.
Also, the fact you even think the way you do, holds you back, you need confidence and self belief, you don't seem to have it, I do.
I can look failure in the face and accept it, learn from it, adapt and improve.
I look at you playing and honestly think you are an average player, you don't take the game anywhere near as serious as I take gaming in general, I have a good sense for finding talent/potential and you lack enough passion/dedication/seriousness to become a great player at the highest level.
I've already lost interest for Rocket League because of my experience, and I don't think I could ever get the interest back because i've already moved onto new games/experiences.
What Anubis said about map knowledge etc, knowing the layout is very crucial to most games as well.
I'm not trying to be cheeky or belittle you, it's just my perspective of things from experience.
