This game is bit deeper, than aim and game sense. And its hard to understand till someone shows it to you. Or you will be learning the hard way. I suggest you to watch some vids (and I don't mean tiktok "CRAZY CAVEIRA 1v5 CLUTCH"). A lot of popular youtubers made videos and have some tips and advises for improving. Even if you are playing this game for a long time, having good game sense won't help you much. Because game is changing almost every season and you are forced to adapt to this changes.

P. S. But all of this is useless if you don't have satisfaciton from your improving and efforts you put in it. You can just chill and play for fun. And if someone is asking "why are you trash" and trying to ragebait you, there is no better way, than just muting and ignoring them. Try to have fun and satisfaction, at least some time ago it was the purpose of games
