Another alternative that I like would be if AF+3 seals (or materials, whatever) were dropped in any old content of the game. (Einerjhar, Salvage, Limbus, even Garrison wouldn't be bad, ZNM, and ENNMs or BS/KSNMs, since nobody is doing those anymore.) I'm sure it would bring back a lot of activity in those fields. After so much Abyssea-only stuff, if our final Artifact stage screamed "back to the origins!" I would really love it.
