The real question is what becomes a crab bow +3, and what becomes the wool cloth +1.

the idea to me that a tier 3 is going to go from 50k->5k and a tier IV goes from 200k->20k i know the math says this should happen I just can't see it actually working out this way.

I'm betting the materia system gets a bit of an overhaul to balance out how they really want the system. They got a nice year long peetree dish experiment on us and got to see how we used the materia.
