You have no idea how annoying it is when you play Team Assault with 3 buddies (4 on 4) in a ranked Team Skirmish game, and once you score, they just go hide in the back corner while holding on to the bomb, so it just stays at Sudden Death.
We were playing in Burial Mounds and it was one to nothing, and they decided to turn it into a "Team Slayer" game and just sit there with the bomb and the game wouldn't end. Our options were to either just sit there for a long time trying to kill them at their respawn point (which made it so even if you killed everyone, they would respawn and be near the bomb so it would go back to sudden death), or quit and have our rankings hurt. That was the most annoying 30 minutes of my life.
