We told you what to play in order for you to properly improve, now that's your problem wether or not you have the motivation to overcome your laziness to go about it, we can't do it for you.
"The problem is i get really impatient with slower maps" is just an excuse to not play those maps, because you seek for a shortcut that would let you keep playing those maps way above your level while sitll improving. Hint: it's not happening.
But yeah, this is a rhythm game, not a whack-a-mole game. Having to wait for the next object to come n shit is a part of it.
