So I am sure I am not in the minority when I say that I dint buy many of the skins from past events which were either available on the gem store or acquirable via a separate quest since space was an issue.
Today however, we have nearly infinite space and the only thing holding us back is time and/or money.
So I hope Anet brings back all cosmetic items that have been released through gem store and via living story so we can still acquire them.
Make them extremely difficult if you have to be still having a way to acquire them will be a very nice gesture.
Some items which were introduced very early on and never had a way to acquire later should also be brought back for new players such as “Mad Memoires: Complete Edition.”
Also there have been an armor set only available in Pvp which was never in Pve, cant remember the name at this point. Would please also like this back, even if it is introduced via the new Pvp reward system.
