I see that the material to upgrade equipment are not upgradeable. any reason why? its the only mats that aren't useable if they reach the max of the level. so we have to sell it but the weird part is that we keep receiving them and we can't do anything with it. - Dragon crystals are upgradeable -goddess (Phamtom )crystal are upgradeable its pretty useless if we keep having them but can't use them. i thought when reaching a certain level you(level 80, 100, 120), you get next level mats...but why are we also receiving old mats...what is the point of that?
