Well compared to a 15>50, its reduced by 80-95%. Compared to crappier mods, that value decreases. Its worth mabye 10-15k to someone who wants to risk the salvage, or just salvage it yourself.
If you payed the price for that 10/10 , too bad.. if not , salvage it and hope for the 10/10.
dont all rares have some mods? even precious or something? or highly salvagable?:/
