I think if Black Mage's nukes weren't so bad, we wouldn't be having these conversations. Like somehow we think giving Black Mage Stone, Aero, and Water nukes will fix the problem with the Spell system on a whole. But sadly it won't. I've warmed up to Aero/Stone being on Conjurer/White Mage I just wished they weren't so Enfeeble/Debuff oriented. Hard to have classes devoted to Enfeebling/Debuffing when every Job has them tied into side effects of Spells or Weaponskills.

I mean I'd be fine with giving Black Mage Stone/Aero/Water and White Mage having Banish/Scourge. Heck if Banish/Scourge did have the Debuff effect of Astral/Umbral down (like old Thaum had) then it would ACTUALLY help Black Mage with the Spell repetoire. But yeah, Spells all around are bad, atleast damaging spells are.

If Fire/Thunder/Blizzard lines for Black Mage were fixed, then I think we could all overlook Aero/Stone/Water on White Mage, even though we all mostly want White Mage focusing on healing. Even then I think the whole elemental wheel needs to be fixed period.
