Ya much like the tools from 1.0 that you gained through achievement, Lucis may serve a similar purpose. They will be an advantage for those who got them but potentially a tool of equal value will be obtainable that isn't as hard to get as Lucis.

With that in mind however there is still the case of recipes needing to be obtained for any new crafter and potentially said materials could be used as parts for housing/Airships.
