I suck at aiming. I’ve tried moving while shooting. I’ve tried crouching. I’ve tried almost everything and sometimes I’ll just get some really good games and get like 25 kills. But most games my kda is 3-17-5 so I need some tips

Am I crazy? Shouldn't duelists be the first ones to be fighting in like every situation, at least entering site and defending? Whats the point of making litteraly anyone else push first like a killjoy, who would be way better defending spik...
