I've been playing since season 6, but I'm still very bad. I would appreciate an answer.
Own key assignment etc. I've already done.
Maybe you just don't have "talent" for shooters. Maybe you should play story games.
Maybe that's not your genre, or you don't like the weapon behavior of fortnite, there are always a few differences between pubg csgo cod and fortnite when it comes to shooting with weapons, e.g. I'm good at csgo with great, but in fortnite i don't hit a shot
Otherwise try it with story games, simulation games or strategic games, everything can be a lot of fun
I also had the same problem but I switched to a cell phone and in one season I could be good for a cell phone because I had experience with a PC and on the cell phone I take a lot of opponents hops there are bad players I would also advise you to use a cell phone switch to pc the players are too good.
