The Doman Restoration was a good inventory/retainer clean up excuse
The side story is nice and all but I really wish they would unlock it. Maybe take away the weekly "goal" so it doesn't feel like you -have to- use it. But I found it pretty useful for dumping all my crap I somehow collect during the week. When it first came out I thought it was a genius move by SE to encourage people to empty their unneeded junk. I was surprised they put a hold on it at the end of the quest chain.
I realise you can sell it all to a vendor but I dunno, the donating thing was nice lore wise, the quick menu was more convenient.
Especially now that I have enough useless materia and fireworks and Eureken pots to fund a new Doman army from Pagos.
