Please make the ability to get Mastercraft Demimateria equal for all classes

[yexie]

I don't think you understand how economies work. If everyone was homogeneous then it wouldn't work. It's the disparity between individuals that fuels purchases and moves money around. You're solution would literally harm the game economy.

I would like to know how exactly THIS would harm the games economy? Please elaborate.

Every class having the same means to acquire Mastercraft Demimateria would not make everybody homogeneous.

Whilst i understand your point, each desynth class has its own specialist item. Just look at ltw desynth and what its done to fieldcraft prices, it's your choice at the end of the day on what you level.
Culinarians get special items only available to them, alchemy can only get certain items etc etc
i strongly suspect that the new trade in artisan items will become desynthable but in doing so they will need to cap these at 1 master d

All the other Demimaterias can be acquired by all classes except Culinarian. Leatherworkers/Weavers only have it easy on Fieldcraft III because they can simply buy the Novelty Gear from an NPC (which was just wrong as is, putting them in an npc AND making them craftable at the same time... crafting them was pointless from the beginning... but that's another thread).
There is really no "special" item that ONLY Carpenter, Weaver and Leatherworker can get. All Weaver and Leatherworker have is a small advantage in getting some stuff (like Allagan Silk and Leather, though those are also drops, so everybody can get them).

Carpenter got the low-end all through desynthesis.
