One of the worst parts is that beating the Towers of Dread/Despair do literally nothing for the grind. I eventually need to get to level 50 in every job and on top of that probably taking until the heat death of the universe, I can only rely on quests (of which I only get one real one per day, and I need to nerf my party on purpose so I can get some enemies I'm still missing) or grinding in two particular areas that get me at most, 27.5K EXP per go consistently when I need like, almost three million. IIRC I'm currently at level 48 as a mage but I still have ten other jobs to grind through for one (1) medal.
