Count me in on as many runs needed to catch folks up.  Inktu'ta is also the last piece I need to finish BiC.
We will need at least 16ish in zone to properly trigger the "4 Exiles" event.
Also, the Cursecaller event demands DPS of at least 10ish players to complete before wiping to the 100k death touch ghosts.
The complete clear can be done in under 90 minutes with 16 people. Lockout is still 4.5 days I believe.
