They could do new advanced jobs eg. Lv 50 whm + Lv 50 bkm unlocks a quest line for the red mage soul stone. As a red mage you can use staves which unlock all whm skills or tomes which unlock all bkm skills or rapier which unlock a preset whm and bkm skills.
If they're using a raipier for a wand and not a primarily stabbing weapon, I'd rather see the job remain buried than bring out such an abomination some have tried to turn it into in FFXI.
