So I took your advice, with the following results. I used my mystic forge stones to craft a mystic salvage kit, direct cost around 20 silver. Salvaged the 180 gobs of ecto that I had in the bank for 352 crystalline dust and 18070 luck. Sold the dust to buy another 180 ecto and made 4 gold profit. Went from 134% to 136% for about 5 minutes work. Judging from the reported salvage rates I was probably a bit lucky to make a profit but, in the long run, until I run out of mystic forge stones, it should probably be about cost neutral. According to the tables I should have made it to around 180% by the time I run out of mystic forge stones. It would have cost about 1.5 gold to use 10 master salvage kits instead, so I'll have to keep an eye on the costs to see if I can keep going after that. Still, thank you for a fabulous piece of advice and I'll let you know if I make 200% by the end of the week.
