1. get good sleep and maybe use an energy drinnk
2. max out yoour gpu performance if possible. fps does make a diffrence.
3. find out your range strength and their rang strength. if you're better at short range than them and worse at long range, use close quarter combat or use buildings and obstacle to your advantage. if they're better close range, stay in more open areas
4. if the rules allow you to hide, hide. lurking can help flush someone out. you can also jiggle a peek to bait an arrow to get enemy location info. it's not dirty, its a game of patience
5. depending on ur playstyle. if you're defensive, use regen. if you're offensive, prolly use speed.
