I had to stop playing MvM because I started to take it a little too seriously. I would have to explain how to new people who go on two cities for the Austrailiums how to do their role, they ignore me, then continue on doing it VERY wrong.
I don't get serious with boot camp because its not paid for and no rewards, so its all in good fun, but Mann Up requires you to pay tickets for and gives rewards, so I don't want to spend over an hour trying to win a match because our scout missed a stuff ton of cash or someone wanted to go sniper instead of demo and proves that he cant shoot a head to save his life.
Pretty much I just stopped, I became that guy who micromanged the team and everything and I dont like being that guy
