Off-topic, there's a little bit of delicious irony involved here knowing that Fran Seara is a "Pro-Class / Anti-Job" player, yet has finished a Zodiac weapon that can only be equipped by a JOB and not the class itself. Based on post history, I'm beginning to think Fran is just a troll though @.@

That would certainly explain a lot...
