I understand that the devs don’t want people to be able to convert karma into gold, and thats fine. But after spending 42k karma on a piece of equipment, you should at least be able to salvage out the rune once you decide to replace it without having to use up a transmutation stone. Just make the rune of [god name] account bound if it comes from karma armor and eliminate the other salvage materials (or make them near worthless, like a single t1 common mat).
Plus, some of us put in our own runes near the beginning of the game when karma items were still salvagable, with the idea that I could just salvage it out and sell or re use the rune if I get tired of the armor.
