Hoping someone here wouldnt mind answering a few questions from a nub .

Im trying to figure out how the armory system works and im hoping theres a list somewhere of optimal abilites for melee jobs and mage jobs to have.

So far ive found out that melee jobs needs invigorate, sentinel, and second wind. Havent found anything so far for caster jobs. Are there any other abilites that are good to have?
