I have speculation, but it's not optimistic ha.

I foresee more class-specific gear that will be mandatory for new recipe synthesis, and will require time-restricted materials to craft (think oaknots 2.0). This system is practically already in place, just imagine if ehcatl sealants were untradeable and all 4-star recipes required untradeable Artisan Offhand.

I'm sorry! /bow
