As much as I would want to agree with you (I'm working towards the luminary on a few crafts right now) it just won't happen. So many people would be enraged that they're locked out of some content because they don't wanna grind out a craft.

I would love to give some extra incentive to get the luminary's (and maybe extend it to gathering where you can only gather some stuff with the luminary), but I can't see it happening.
