haha in all seriousness. SE has already proven that they are not willing to make jobs that can be both heals/dps. They have also stated that they did not like how the only heals/dps class turned out (acn), and that they would not go down that road again.

Blue mage is a very difficult class to put into an MMO universe because of 1 major issue. Traditionally, blue mages get their new spells/abilities from enemies they find in the open world. They are not related to a character's level in any way. This doesn't jive well with the standard MMO abilitiy progression. If they do find a way to do it, then it will either be extremely innovative, or a massive lore killer.

If I wanted to find a job that could use a whip as a weapon, I would think of something like a Trainer from FFX-2. They didn't use whips, but they are common item for training animals. Only problem is we alrdy have a pet class so........
