In a CT run we had a Marauder queue up in all pvp gear telling our other tank to solo tank and he'll dps.
We ended up vote kicking him since he was being an all-round jerk. However, when you vote kick someone, it doesn't incur any duty penalty, so he was free to re-queue in progress back into our run.
What's the point of vote-kick, a feature to punish people who act negatively in groups, when it doesn't provide any real consequences?
