This does require you to click the door and chose to go in, but it's really not hard because Ix'DRK stops to cast stupid spells, and he'll lag behind you, or give you time to click.
Once you're in the teleporter room, just kite it around the teleporter and survive until the 2nd person comes back, (Usually a BLM), and have them nuke from the teleporter. If they get hate, just zone down, rest MP, zone up, and continue to nuke.
