I think to please the elite players, they will nerf these.

Before the HQ wasn't sure even if you use all HQ mats. Now, with synth reform, HQ item yield rate must be controlled by the mats yield rate.

Same thing with materia control, lots materia fly around in the market now. I think they will try to reduce it to make it's more rare or rewarding.

aww lots works to do before the patch / . \
