How about this, we're thinking in terms of melee weapons. rdm, mtk, whatever, they're magic classes. The important thing is getting the feel of the class right?

Try this. Fully int based. Whether it actually uses its weapon in a traditional sense is another story, but here's my take. In the space of time a melee fighter swings his weapon, the rdm/mtk slings a spell. In essence, it's a war mage.

This settles the issue with stat distribution. Now you can design all of its abilities around the idea that it's a fast spell slinging monster. This leads me to favor the mystic knight over red mage. I just can't imagine red mage as a front line fighter to begin with... at least not as a tank... rdm, to my memory had always had that Jack of all Trades going, but I feel like making it lean towards a dps role would be good for it. In either case, I like the idea of them soaking up elemental damage, but atm so the bosses even deal a lot of damage? Either way I'm spit balling. Seem sound?
