This one I mean is your focus, u change your aftermath build elements to the one u think is better and keep changing. It make u lose the chance to see full/complete build of the one u try to make previously and lose the chance to know how much damage it deal at max. U lose alot crystal this way. Try focus on 1 build ATM.
This one I mean is your time, u see if u already have all information time consume to craft 1 build will not be too long, like u did now, u looking warrior helm with rage set affix, it took some time right.? If u know that u can just jasper wizard hat to warrior helm and use amethyst to get rage set it doest take that long time.
I though I already separate both advice with DOT lol. But I think u take both advice as 1.
