So maybe its been brought up before but I see it as a no loose situation for most players and ANet.
When salvaging a level 80 item, based on its Stats you would stand a chance at getting a Fine T6 mat back with the other items used to create it.
More casual players are happy because it increases the T6 Mat pool and lowers prices.
ANet would be happy because it would follow the same rules and Sigils and Runes, higher level Kit, the better the chance of getting a Fine material back, therefore increased sales of mystic forge stones and BL salvage kits.
