A system that is put it place so that Anet still can get money from transmutation stones and where we are able to keep our skins easily would be very handy and valuable on both sides. Maybe a system could be put in place where the skins can be removed off of gear using a transmutation stone which would then be stored easily through a tab on your hero interface could work as we would still have to buy transmutation stones but it allows us to keep our skins
