Been working on getting my jobs to 90, after running out of daily roulettes my only options are to run dungeons near my current level, the "Deep Dungeon" styled content which includes Bozja/Zadnor, and FATEs to get the weekly challenge for a couple decent bumps of EXP.

That being said, FATEs are fine if you really want to take your time leveling, though I think there needs to be some incentives to grind those instead of running a dungeon for the fifth time with trusts or players. Maybe include a FATE board, similar to hunt boards, you have a daily FATE board, limit 3-5 a day where you do a number of fates in a given area for a very large chunk of XP, about like 2/3's of a dungeon of your current level.

Let the rewards for those be allied/centurio seals, and of course quantities of gil.
