Yeah he's right, I'm already bored out of my mind with playing this game and I could care less about ranking up.
There's a way easier way to rank up though.
Set up a game for first to 15 kills
Set a turret up at your friends base, get five kills.
He does the same to you.
Then one person gets 10 headshots using his sidearm.
You get the sidearm badge, headshot badge, and the no negative points badge or whatever it's called all in one game.
You can keep doing this with other things as well, just be smart about it. Just killing eachother one by one trading off won't do it as fast as that.
