I think devs should make the transmute station free and if you want to reconstruct then that should cost shards. Here is my thoughts on this, with as offten as devs are making changes to armor sets or even classes and skills its just making me sick that I have to spend so much time getting shards to get an armor set set up the way I want only to have the damn rug yanked out from under me a week later...
Just make transmute free.
