honestly, idc about either one of them.
I do respect that red mage has been around since the first ff. In that way, red mage and thief both need to be around.

But I would like something different, a class that not the same as the other in usage.
Dark knight looks cool, plays boring.

I want something different. Something not like the other classes already in the game.
Musketeer does sound interesting.
Other things that would be cool and play differently, like chemist, blue mage, even ninja.
