only thing i can think hes doing is rune farming. this is server dependent on the sell price of runes on the cx when determining if its profitable or not but basically make the easiest tailor, weapon-smith, outfitter, whatever gear trade you got and then salvage the crap out of them hoping you get rune fragments to resell on the cx at major profit. like i said earlier the profit of this is dependent on your servers cx prices for runes, my server they go for 80s each sell now, but other as much as 10g sell now. The 10g server being the obvious profit maker
also on average its about 5-8 salvages per rune fragment less if your lucky
