You are getting good with the controller, I see. I prefer keyboard even in driving games and while Rocket league is not a racing game you still need a lot of control and precise driving. I learnt to do it with keyboard and an year ago I tried to change it to see how well I can do with the controller, I sucked so hard at it. One of the main reason is the controlls are a bit complicated in the game, you have some air roll buttons, a jump button, a boost button and the ususal left right, forward and backward with some ocassional powerslide. It was too much for me to relearn and I just didn't bother to unlearn the controls. (What I learned from that entire episode is that if you want to switch, better switch before you have dumped 1500 hours learning it from keyboard...lol)

Happy drifting, bro!
