A lot of people I know are still on Divine Might, or don't have CoP finished, so they're not at the point to worry about this mission yet >_>
Anyway, I was RDM/NIN, he was PLD/NIN. The first phase of the fight is mainly just a long slugfest for the PLD, and a repeated sleepfest (on the Orbitals) for the RDM. Only thing to watch out for is the Exoplates' Phase Shifts, which happen at every third of its life and become progressively more damaging. Keep a close watch at its HP and make sure you each have fresh shadows up before it uses the move.
Second phase is harder because there's no real way to choreograph it; it will always happen differently; Eald hits like Hundred Fists here and has nasty TP moves in this phase. Best thing to do is have the PLD keep Sentinel and Invincible ready for this phase (Eald only casts AMs on the 1st phase, so you're not going to need either of these at the end of the 1st phase fight), and have RDM whip out Chainspell nuke. It should go quick, but won't always go your way (I had to do 2 tries before I won this)
