play more?
also i think you posted this on the wrong forum (this is the osutaiko forum) but i suppose the same goes across all gamemodes.
This is just what worked for me, play maps that you can pass but feel like you could FC given enough practice. And of course don't expect the improvement to come quickly, as someone once said "it takes hundreds of hours to be good at something, hundreds more to master"
As long as you take your time and don't worry about how fast you improve then you will see results. Hope this helps even if its a late reply
