I think on next expansion, they should bring pet based job, Puppetmaster + Beastmaster. And another magic based attacker to complement Black Mage. Perhaps evasion based tank. And maybe turn Geomancer as a healer, now that would be interesting. This way we could have at least 2 pet based DPS, 2 magical DPS, and maybe another healer or tank. Runefencer would be great if we don't already have Dark Knight.
