The Possible Red Mage Solution

[Duelle]

If you place a fencing guild anywhere, I would like it to be Ishgard. Fanciful fencing matches sound like a perfect pasttime for Ishgardian nobility.

I'm glad to see other people are coming to that conclusion.

That said, I'd expect there to be some sort of passive stat conversion if you're even thinking of implementing a hybrid of any sort. This applies to any hybrid, but yes RDM needs it more than others simply to create that versatility without a) making the job overpowered and b) shackling it to roles it has no business doing (read: tank, heals, buff-botting). Hence my suggestion of having fencer be at the base a DPS class with the RDM crystal bringing in the utility in a way that would make sense for the job while entirely avoiding the problems RDM's last MMO incarnation ran into.

Take your pick, with enspells or without.
