A request from a Ninja.

[Nalien]

This creates the requirement of a lot of work for little in-game benefit

I think it could make for some form of additional "content" to have such a system in place. Granted, I'm thinking more about what I suggested with Bard and Summoner for that (do Sephirot, get drop that you equip to have Sephirot-Egi), but it holds true for Ninja as well. Rather than going out and getting one weapon to use for a glamour, you're getting two. They add a new weapon that you prefer? Might work better with a different weapon in the offhand so you can go out and get that. Perhaps it works better with the Final Coil weapon, so suddenly you're out doing Final Coil.

It's not a massive piece of content, but it's something else to do, and glamour is the true endgame after all... I'd actually rather SE make new options like this, than just continue to provide us with more of the same... Ideal world I'd want both, since more options are never bad, but given the choice between one new set of weapons for every job, or a new way to customise all the existing weapons in the game? I'd opt for the later. I'd gladly pass up a new set of glamour options to instead have more options with the existing glamours. They add a new set of daggers, I consider that vs what I currently use and that's it. They add something like is being suggested here? Suddenly I'm reconsidering almost every dagger in the game, and the content involved to obtain them.
