Yeah I don't think Berserker would work really, Beastmaster has Berserkers AF and Warrior has it's abilities... So um, BST/WAR=BER? lol

I like the Geomancer idea and the Chemist idea, but I think if they introduce Chemist it should have elements of alchemists too. They shouldn't rename it alchemist, because alchemy is a guild, but it should have mix like job abilities, or just other abilities that are directly linked to your crafting skill.
For example, you could create weapons by combining different items from your inventory, using the job ability "mix" or maybe "synth" would be more relevant to FFXI. After making them with the ja, they're tossed at the target as an ability rather than an item...
Mmm, I think Geomancer would be a good introduction to the game. We are kinda running out of reliable healers really. The only downside is that it would be expensive and probably require crafting if my idea was implemented.

It's like a mage class that uses items instead of MP.

Heheh, they could equip any item in the ranged slot, and throw it like Amarant does :P
