Yes, please.

So many jobs have these beautiful artifact sets limited to just their job, but are easily deemed irrelevant the minute higher tome/raid/crafted gear is released. I want to continue using the pieces of glamour, but I can't do that when my healers all have to share gear, or my tanks all share gear, and rather than use that beautiful AST AF3 set, I have to settle for a glamour that projects onto all 3.

Same for BRD and MCH. I want my BRD to have her AF glamour for quite a while. But once I get MCH to 70, I'll have to change it. And with the other DPS jobs as well (save for DRG and NIN).
