I just leave the game when i dont pick Peacekeeper or Wingman early

Absolutly not true. I never use peacekeeper and wingmen, at least not in mid to lategame when I find weapons that suit me better because I hate oneshot weapons. Just because they are concidered as the strongest weapons doesn´t mean they are the strongest for me. 

And obviously I care for winning otherwise there is no point in playing competetive games like apex but still I wouldn´t pick those weapons. And belive me or not, I still win 🙂

I see a lot of people, even in my own circle of friends, who just pick wingman / peacekeeper because the internet says so and then they suck. It´s a fact that you need a decent aim skill for weapons like peacekeeper and wingmen and if you don´t have good aim, you have to find your strenght in other things like movement, intelligence (outplaying) and so on.
