I'm very sure you can't Azeo, there is I believe that problem that if there are less than 6 people inside then the whole GPQ is terminated.
But well I believe we need to control at least the following:
1. low lvl char (lvl 30 and below)
2. a mage with max tele (or 17 and above I think)
3. someone who can haste (i think this is needed for that one part but I'm not absolutely sure)
I'm not sure if there is anything else we need though, but doesn't look like soloing it (even with multiple computers) would be feasible, unlike the PPQ ... ^_^
