Most Useful Class (Completionist ONLY)

[Secret Weapon]

There is no ONE most useful class, they all specialize and have a different role in battle.
However I'd otherwise go with Red mage.

Yes each class has it's own role in battle, if they had no use then square would've cut out partially useless classes throughout most of the game (*cough* Scholar!). I'm saying in your tactics and the way that you fight, what is the most useful class in your experience/opinion.

I think What In Your Opinion Is The Most Useful Class (Completionist ONLY) too long and dry of a title. It's titled that way so it's open to however you'd want to explain it, of which you didn't even leave a sentence after why the red mage is the most useful.
