Lots of us worked hard to gain these items and although they have less use they are still like trophies for our constant efforts raiding. Some took forever to get. Some have never and will never be acquired by some people. It's a shame that we have to decide between keeping a trophy or making room for something new. I doubt we'll see any more vault space ;-( but it would be nice if we had something similar to the exotic blueprints. The new light level system could make that slightly abusive but if it were just older raid items or if the newer ones were only 300 light it wouldn't be broken. Especially if the Mark cost was high.
