No, you don't have bad team mates, you have a toxic attitude that make the game not fun for people.
Sure, sometimes your team can let you down, I know this from personal experience due to the fact that I have been banned for being Toxic, several times.
But, you can't be solely blaming your team. You have to sit down and think "Okay, what is going on, what am I doing wrong, and what can WE do to fix this."
Besides, unless this is ranked (even if it is), you should never get to the point of name-calling.
and like Inkling Commando said, we don't think "We HAVE to win" we think "We should have fun because this is a game that we love and we should all be trying to get along".
It's not like you will ever go pro, so just play the game and stop making life difficult.
