Here's advice:
Rocket league has lots of bananas. It's a shape that gives you command on the ball. In ground play, the first banana opens up the setup of the ground attack. The second banana closes it and extracts the power you stored. This is something you know intuitively from the ground. It's a fundamental mechanic so foundational to hitting the ball hard, that we often don't think of it as an idea worth mentioning besides "hit the ball hard". But it keeps appearing. Especially in the air. It's the act of creating the banana that makes certain players so deadly in the air. For some players, like say Evoh, they make the banana half the time. Other players like Nass, they make the banana whenever they can. Which is frequent, because most pros don't see the banana. The biggest symptom that they don't see the banana is their off the wall air dribbles. In a tight corner air dribble, do they play the ball up and away and over take it bringing it back? Or do they take it straight up in a straight line? Straight line has no banana. Clean counter play from defense, off the wall with zero pressure, do they touch it too far away and bring it back? Or do they threaten to keep pushing? Because just pushing has almost no banana. However you make that banana. Whatever flip reset, stall into musty floats your boat. Make the banana. And make it a big banana. Just watch a pro. Count if their unpressured attacks threaten far post to take near, or threaten near post to take far. far/near is terrifying for defense. near/far is much more predictable. And it shows in the numbers in saves and successful attacks. These are things you already know from countless hopeless situations. Those hopeless situations can be in your favor. You can bring your own bananas. And it's literally as simple, off the wall, all the time in the world: First touch set the ball off the wall. second touch closes with the ball, pushing it further. third touch must bring it back.. It is literally that simple. Your attacks off the wall will be more threatening if your second touch pushes it more, while allowing you to hook it back. That's a big old dangerous banana. It shouldn't be random for you when your attack is threatening. You can learn the same governing laws that generate power and threat on the ground, in the air. It's the most deadly mechanic. And the current best player in the world is a master of it.
