There are so many sidequests everywhere tho, if they increase them too much no one would do any other content. How much experience should a side quest give? 7 or 8% of a level per quest? If you see how stacked some areas are with them, that's a lot of xp.
I haven't really done a lot in this game in terms of side quests tho, I really don't like the go here kill 2 or 3 (or however many) kinds of quests in games, I feel like it's kind of low bar in terms of compelling gameplay ideas.. some of the go hear and wait quests really grind on patience. I liked some of the ones I've done tho. I wish they offered something a little more than a splash of gil and next to nothing xp tho.
