Some things I noticed weren't mentioned. Fates, Roulettes, Hunt Log, and Challenge Log. Especially at the lower levels the hunt log shows its value, lvl 1-15 on any new class can pretty much be attained with just it and a fate or two sprinkled in to get over the lvl 10 line. When your still queuing as DPS fates are a great way of filling up the queue time with quality xp, or just when your not in the mood for dungeons. Roulettes at this point of the game Leveling and Guildhest are about it for you. While leveling keeps its value to 60, sub 30 the Guildhest one still gives enough to be worth it. And lastly the challenge log, unlocks around lvl 18 quest starting in Limsa's Drowning Wench, resets weekly and gives you more bonus xp and gil for doing what your doing to level anyways.

On a side note lvl 1-15/20ish side quests are pretty much throw-aways since you can level super fast then without them, when you start getting into youe 25 + range sidequests their value to hold for later DPS jobs goes up. GL HF.
