Okay. That was a problem when this was actual content as well.

Coil is HARD. Doing it in Duty Finder and actually getting through pretty much never happened.

What everyone does now, and what I will recommend that YOU do, is you get a group of friends out of your FC, and go in unsynced at level 60 to roflstomp the place. Or if you're brave, do it synced for the full experience.
