Tried to get the hydrocane for the underwater breathing ability.  Had a friend willing to run me through.  4 times the boots dropped & the dagger dropped once.  On the 6th time that we tried to reset the instance, we received the message about too many instances.  Did not get ported anywhere, just could not get into the instance anymore.  Will try again another time, but rather painful to get to gnomer as horde (long walk).
