As it stands, Paladin is the only job able to equip (and glamour) a separate offhand weapon. This variety allows for a lot of cool combinations for people to put together neat sets, what I would absolutely love is that same glamour variety to also be accessible to other jobs that use two weapons.

Some examples off the top of my head: Red Mages using a different crystal focus, Ninjas Monks and Dancers using separate weapons in each hand, Bards and their quivers, heck maybe even allow Black Mages and White Mages to glamour old 1h wands + shields. The only one that might be problematic is Samurai and their sheathes, since some swords are curved or whatnot. (then again SE very clearly isn't shy about letting things clip)

Now I'm not a game developer or an expert so I cant really say how feasible a system like this would be, but I know most of these are stored as offhand models already. Maybe a solution would be to add the subcommand "Glamour Offhand" to available weapons?

Again I'm no expert but I'd love to hear more people's thoughts on a system like this.
