I tend to prefer more down to earth weaponry, which I think they're running out of?

In that regard, one-handed axes, both one and two-handed maces are something they could still add, as are dual swords, which they could combine with/into a double-ended polearm (akin to these used by FFXII Judges), for added novelty.

Me personally, I'm a huge sucker for swords, but I doubt we're getting any more sword Jobs (aside from the aforementioned dual swords, perhaps?)
