Lucis Items should Glow

[Niwashi]

so if a Lucis requires all 8 at 50, how would a dow/m have a Lucis that is forced to buy a prism for the Lucis?

Huh? Lucis are crafting tools, and as shintashi mentioned, they generally require having all crafting classes at 50 to make them, so anyone with a Lucis tool must have the ability to make their own glamour prisms. DoW and DoM don't have to craft their weapons, so they may not have the ability to make their own glamour prisms (unless the player has diverse interests and coincidentally happens to craft as well). Hence Lucis tools can be more readily glamoured than Relic weapons.
