I think it's about time for a vote kick option.
I just sat in a game for more than 10 minutes at a pressure plate while the party leader went AFK unannounced. So our only options are either keep waiting or leave the game for Haven and forfeit our Heat. How is that fair? How could a simple option like this be over looked?
You really don't even need a vote kick option. Perhaps a 10 second auto kick timer that starts when a party leader goes into the sleeping animation?
I doubt it's a stretch to just add the same option that you're given at a ''sub-town''; e.g. Moorcraft.
If the whole party isn't on the elevator to go down you'll get an option to go alone, or to invite others in the party to go with you while the other person is left behind.
If they just kept that option for every elevator then there would be no problems. Someone's taking their sweet time on purpose? Take the rest of the party and ditch the jerk.
