I'd much rather see them add quivers for our ranged slot. They could enhance abilities in some way, add additional effects or just simply add stats. (Current game, "stats" would be the easiest to add).
  • Basic ones (like all other gear) could be crafted. Yay economy!
  • Better ones could come from dungeons or raids.
  • They would be an equipable, non-consumable item, meaning you get it once and keep it. Or turn it into that spiffy fire materia IV you've always wanted.
  • They would go into your offhand armory chest, making inventory management a non issue (With all classes 50 you barely half fill it).
