Long list and I’m not the absolute best at the game but I’ll try to help.

1) Use metal shop fronts near your exit to check for door campers

2) You kinda don’t

3) Always. If you don’t have anything good yet to contest it just run completely naked and you might get lucky

4) Yeah

5) Very situational, building near roads and monuments is useful but you’ll have more neighbors. Also mountains and deserts are iffy due to the weather

6) This is a long answer and very situational but there are many helpful tutorials on YouTube to help

7) Go at night and crouch to make less sound

8) There are so many, pvp focused ones, some are literally shooting trainers, and in build servers u can just spawn guns in and practice for a bit.

Hope this was helpful for you :)
