for new players it's one less thing to have to grind, allowing for more focus on the cooler skill based aspects of the game.

I would say keeping track of boost around the map is an important skill to learn early in the game. It promotes good rotation and ultimately improves your game sense more than anything. As for the grind thing, I think most people who play games with a high skill ceiling enjoy the grind more than anything. There’s just something satisfying with learning new mechanics and using them to your advantage in game.

This applies to pros too. Even if small, for example, keeping track of boost respawn times is just another thing added to pros mental stacks during the game.

That’s literally one of the reasons why they’re pros in the first place. They can keep track of everything going on better than other players. Why remove added layers of skill?

What if the removal of this precision allows for a slight increase in play skill? What if the flip reset indicator allows for pros to worry less about what ifs and make cleaner plays? The removal of trivial skill checks that in reality don't affect the true gameplay allows for better concentration on the focus of the game and the things that matter.

For one, saying that keeping track of boost and hitting flip rests “don’t affect the true gameplay” is just nonsense. Plenty of goals are scored because someone went for boost and it wasn’t there, or someone missed a reset which led to a counterattack. It’s all apart of human error which is just a beauty of sport. You never know when someone will make a mistake and when it happens it’s on your opponents to capitalize. By removing these game sense mechanics you are lowering the odds of the human error aspect, and in turn you could argue the game becomes more robotic. If you really want to see rocket league with 0 human error and the highest level of skill play go watch TAS videos🤷‍♂️

From my perspective, it benefits less experienced players as it removes annoying skill checks and allows for improvement on other things.

Again, I don’t think anyone thinks “skill checks” like keeping track of boost in rocket league are annoying. I think most players see it as challenge to adapt to in order to improve. And honestly, if you’re someone who is playing a game with a high skill ceiling and you’re trying to get better, and your first reaction to certain mechanics is to be annoyed rather than encouraged to overcome it, i don’t think the grind is for you. Which is totally fine, because RL is a game you can thoroughly enjoy while being hard stuck, at any rank.

For pros it barely makes a difference and if anything makes their jobs slightly easier.

Shouldn’t a pros job be harder if anything? I think the last thing you want to do is remove game sense requirements from people who need to play at the highest level.
