TH is a bonus, by nature. That's why not ever job has it. Giving 'every mob THII on drops by default' removes the idea of it being a bonus.
Think about your suggestions before you post them.
As opposed to pandering to the population of Casualville players and their crys of "make relics, mythics, empyreans available to everyone with no input, because this isn't really an MMO"?
Maybe they should stick a Moogle in towns and let you get any item you want just by surfing a menu and selecting it. Oh wait, that would be too much work.
