Here's some facts, just so some of you idiots actually know what's going on, when you decide to fight 3 on 1:

1. Your team mate, is most likely fighting 1v3.
2. You're all doing an exceptionally good job of helping the enemy get revenge.
3. The enemy are capturing objectives.
4. You're losing the game.

I don't know how many times, I've been stuck against 3 of the enemy, spamming the help button, only to die and the camera pan to my team mates all spamming attacks against one enemy, who have all happily ignored calls for help. It's at times like these I take a note of their names to make sure next time I'm in a game lobby with them, I leave.
