There is a warning that appears when you try to salvage an item of a certain rarity or higher. (I believe it’s green or higher)
Problem becomes apparent when you’re doing chain salvages, especially on PvP gear, all of which is exotic. There’s no way to do this easily other than double-click the kit, click the item you want to salvage, and move your mouse to the warning screen and click “Yes, I do want to salvage this item.”
Please create an option to turn this warning off. Not all of us are interested in carpal tunnel.
