Not quite sure, but i also don't like the fact that you can party up with more than 4 people and go play team slayer or something related to that.
It's not quite far, because sometime one of their party members can just suicide, or find another way to just make you lose to benefit there partys team.
Maybe calling my team out, and where to go to kill me, etc.
They should defiantly keep it to the max amount of team members.
But in your case, sorry I went off discussion really lol.
That sucks, and its never happen to me yet, but i'm sure its going to happen eventually.
