The game doesn't need any more EXP boosters. We have two items. One that goes to lv 25 (I assume will be raised to 30) and one that goes to 30 (I assume may be raised to 50-60). There is also the Armory bonus, Rested bonus, FC buffs, Food buffs, Guildleves, First Time bonus, a Mentor bonus, Hunting log and Challenge Log.... For crafting and gathering classes there is also a xp booster bought with seals then scrips, and chain bonuses (which are more useful than the battle class ones due to how HQ works). We have every imaginable exp boost except buying the level up with real money. Do we really need to go that far?
