Unfortunately you'd run into issues with people who like the enameled look on armor and wish the new armor had a flat color look. It's kind of unfortunate but it seems they've moved on from modifying 1.0 gear (minus Darklight anyhow)

Ideally they'd give us 3 variations of each model - one that dyes metallic, one that dyes matte enamel, and one that dyes glossy enamel (e.g. PLD AF myth variation or the Heaven's Ward uniform)
