I know a lot of Blue Mages complain about the work involved in obtaining our huge spell list, and then not having access to it all at once like other mages. I realize, as do most others, that granting full access to the spell list would have ramifications on job traits gained through spell combos. The mechanics of the Blue Mage job seem to disallow any chance of gaining access to all our magic at once. I think there could be a simple solution, however.
If the main concern is having unlimited access to job traits, why not just change "spell" set points to "trait" set points. That way we could have full access to all those spells we worked so hard for without the mind-numbing annoyance of navigating a huge spell list to swap things out, but not become all crazy overpowered by unlimited job traits.
This would add a little more flexibility to situational spell choices and ease/simplify the spell selection interface.
