Lot of tanks. I took GNB and PLD to 80, as well as SAM. I had been playing a Red Mage, but I felt like it was too reliant on the caster part, while the melee seems tacked on.
I will say this one negative thing about dancer: the lack of weapons is appalling. GNB (and Blue Mage?) has this problem, too. I cannot fathom why SE didn't - in the least - go back and add Primal craftable weapons for these jobs.
