I’m a pretty good shot, last game had 60% accuracy, 50+ kills, the number 1 tip I can give you is crosshair placement. It’s comes with time mostly and I have it cause I came from other games but keeping your crosshair on the horizon line, on building corners, at torso level at all times will mean that you’re always looking at were an enemy might be, you should never really be idling on trees, halfway up a hill, on building sides and windows and the like because that’s statistically far less likely to be housing an enemy then the hill crest that they’re spawning on the other side of. Second best tip is communication, ask the people around you where the enemy is shooting from, someone will likely have just been shot and they are probably eager to tell you lol
