Leveling is already a massive joke and the exp boosts just make the game feel poorly balanced, fighting titan at lv 44 or having a mish mash of skills from 60+ but not 50+ cuz of the areas and job quests are locked making progression bizzare and incomplete. example being as SMN i had acess to Aetherpact and Ruin 4 before deathflare and tri disaster due to being overleveled.
