I teamed up with someone doing this dungeon after I finished Aggrobah. I was somewhat surprised to find that I had teamed up for a dungeon that didn't have a fight.
Not only is team-up for this dungeon unnecessary, it can also hurt the people using team-up as well. I walked out, ported home, went up to the kiosk in my home, and I couldn't team up for another 8 minutes. Now, this might not matter to those who don't work for the badges for Derrick Blaze, but I work for those badges.
I hope Kingsisle can change this when the next update comes out.
