Do you feel Supras are worth it?
Have been occasionally try to get demimateria from artisan spectacles and it's so much work. The demimateria are also incredibly expensive and you need too many of them to make the stuff to trade in for the Supras. The Supras' stats surely don't represent a large enough jump in stats that warrants that much time, work or gil.
To be completely honest, the thought of having to make hundreds of spicy tomato relishes just to get a handful of demimateria sickens me to the point where I'm ready to quit. The artisan was a grindfest, but it involved no RNG. This whole desynthisizing system has taken a lot of fun out of the game for me. I love my crafting jobs, but I'm having a very hard time convincing myself that these Supras are worth the effort.
