I really want to like this game. It's not seemingly allowable.
You're new. You suck. People call you a noob. They tell you "No one wants to play with a noob".
They kill you. They kick you from the team. You then are left to wander around until you get a mission that you get outnumbered on. They see your score and instantly quit the team.
There is not a place for a new player in this game. Community doesn't like new people.
Unless I guess you are some sort of prodigy.
