You might have a valid point. Might be time to chill, learn to aim, and learn how to handle a rush.
Like competitive, wingman is a team-based mission. Operate in a team, get someone who can play with you regularly, see what works, switch things up. The general rule is to be comfortable with yourself, then you will learn to appreciate patience even when under pressure. Once you have trust in yourself, you will learn to have trust in other players and I mean random players.
Look, life has one simple rule and that is to ask. You will never know anything in your life, talking synergy here, without asking questions and by this I mean to communicate. You know communication is a two-directional process? If your teammate is mute or an oaf, keep on talking, give intel, he/she will be listening.
This stays a game, there is no real life or (‘and’ going by PUBG lingo) death situation here, but the same life rules apply to win or lose, pick whether you want to win more or lose less.
Talk.
Because this attitude,
Really just two 1 V 1's the whole time.
is indicative of individualism.
How to aim, how to handle rush, that is simple positioning, being tactically aware and not giving your position away by 'running', and to change it up by changing strategy round in-and-out. Learn you smokes, mollies, nades and pre-flashes, YouTube is a educative library, search it.
EDIT:
The radar is a tactical tool, use it.
