Hello,There is always a trouble for salvaging or not salvaging items.My proposition is about WARNING before salvaging.When that message pops for exotic things "You are sure you want to salvage?" you can add a RED warning message exactly down saying "tThis item is probably needed for another collection or upgratting" bla bla.That way will be clear what items will be important to not be salvaged.Thanks in advance, will save you much time from supporting also.
