idk, I'm going through the job list in my head and most of them tell you something about the job just in the name

Paladin: holy protector
Warrior: eh..a stretch
Dragoon: Dragon fighter, a FF staple
Monk: melee fighter
etc

Viper: twinblade specialist..?

I don't know, I can't help but feeling we're missing the core identity of the job that SE is hiding for now.
