I have noticed that there are still a lot of items floating around that have not been removed or converted since ARR started. Some of these items include:

Beastmen Currency (previously used for relic weapon quests)
Hamlet Defense items (Militia Swords, Stiperstones, etc.)
Deaspected Crystals
Faded Page
Wanted: Gauwyn the Gannet
various event items (Blue Bombard Ash, etc.)
various crafting materials (Buffalo Leather, Wolf Hide, etc.)
"entry" items for primal fights in 1.0 (Inferno Tapers, Unmarked Keystones, Vortex Headdresses)

I am afraid to get rid of these items because I suspect some of them will be used in the future, but it would also be nice to have the inventory space. What should we do with these?
