This is the only place I could think to add this, sorry if its in the wrong spot.
Currently, on Softcore Amercia servers, Fiery Brimstones are going for 244,xxx gold.
However, you can sort by legendary level 60 armor and score some buyouts around 175000-225000 gold. Once they are purchased, salvage them, put the Fiery Brimstone on the commodity AH for a reasonable price and it will sell within seconds, netting you an easy (typically) 20000-25000 gold for little to no work at all.
I know it isnt much but it could cover your repair costs between games!
