Conjurer is Druid. It's all about communing with nature to utilize the raw elements themselves to protect, revitalize and even to quell threats.

It just happens to get a bit more of a Priest focus after becoming White Mage.

As far as Hunter/Ranger goes, we have Archer.

It just happens to get focused into Bard after level 30.

That said...

I'd love to see Beastmaster (As a non-Limited Job).

I think Bow Mage Sniper could be cool too.

Also, I think it could be neat to get a shapeshifting job similar to WoW's Druid (I know someone wanted something akin to Vincent's Chaos form. Lorewise, there's potential for SMN to shapeshift, akin to how Dreadwyrm Trance and also Ysayle becoming Shiva works)
