Something that came up in conversation today that I thought was interesting, was a YouTube video, showcasing some visual modification, making the Ninja look more like an advanced Rogue. Third-party aside, which of course, we're not advocating, it's an interesting way to diversifying and personalising one's character.

Making your White Mage more in line with a Geomancer with rocks and nature spells instead of bright lights? Your Ninja is more a Rogue with abilities more akin to Riku (Mudras become Mixes). Fire-Based Black Mage, Thunder-Based Black Mage, Ice-Based Black Mage, your choice! Your monk becomes more of a kicking-focused fighter, or has your Dark Knight redeemed themselves as a White Knight?

A glamour for your abilities, so to speak.
