Seriously guys?
I know you said beforehand that you'd be moved outside if you d/c'd. It returns you to the instance initially, so the server knows where you belong. Why the hell can't the party leader re-invite so you can re-enter?
This is seriously lame design, since the R50 dungeon is designed for 8, and it's not like the game has a stable client, or stable servers, or is in other ways totally free of defects that regularly cause people to crash/disconnect.
Way to fucking ruin it.
