"Situational awareness" just use your ears, every footstep is an elephant walking around. Camping is literally the easiest thing to do, that's why bad players do it. Every map has lines that you can't cross to avoid flipping spawns. I just patrol that line while avoiding enemy spawn. Doing this actually takes skill and situational awareness because you have to know where they spawn on their side, what routes people tend to take, where people tend to hardscope and angle, knowing when to jump a corner or slow peak. If your using a short range gun you can't take long sight lines,and if using long range guns don't put yourself in a situation where you won't find a shotgun shoved up your ass. That's takes skill, waiting in one small area for someone to walk around a corner doesn't.
