Do edit courses and don't give up keep trying
Look at pro players like tfue, they do specific things other pro players don't do, like always peak, find exploits etc. You need to outsmart your opponent to also be better at building, and if you're able to get highgroynd quicker you must able to crank 90s fast in any direction and also be really good at tracking. These are just a few of my tips from when I used to play fortnite and quit back in season 7. (Had around 1300 wins).
Just stop playing fortnite
keep on practicing
keep practicing and try doing edit courses
