The game doesn't need more ways to generate gil, what it needs is for the damn grind that was added to Gathering and Crafting to cater to greedy players to be removed so players can be self-sufficient with a reasonable amount of effort. This will in turn cause prices on the MB to drop because more people will be able to gather mats and craft stuff.

Gathering and Crafting were already stupidly grindy before Heavensward, now it's just crap with bloated mat requirements for recipees and so many essential materials walled behind unspoiled/hidden nodes.
