3.0: Elemental Weakness/Resistance?

[Estellios]

Or, it could be like FFXI..

Hey guess which game had content that specifically excluded jobs? Oh that's right FF11. Why take melee to anything when AOEs are a pain in the ass or instant death when we can just bring RNG and BLM that not only stay out of AOE range but do more damage anyway. Oh sorry PLD these enemies 1-shot even you we need a NIN instead.
