I don't think I've done a single side quest with my later classes, besides beast tribes and class/job quests. Experience is so easy to get, what with the armory bonus, the Helm of Light, the Brand-new Ring, Roulette,FATES, leves, and, for the first 20 or so levels, just killing stuff. I have a ton of side quests th T I haven't needed to even glance at. The game practically throws exp at you once you have a class hit 60.
