Definitely alt. Especially if you like SMN and SCH, 30 int vs mnd but also you can play a different race with another 5 or 6 points higher than the other. I play roegadyn sch/tank/melees and elezen smn/blm/brd.

Even in 2.0 this game throws so much xp at your first job, and now it's downright laughable to level jobs.
