Marketboardable things in Misc. like Sylphic redleafs, ixali ebonknots
Other marketable items like dormouse pelts, ladybug elytron
etc.

And then untradable items like vortex headdress, inferno taper, unmarked keystone.

I know some items were re-implemented into the game during the 2.0 days. But we're in 4.0 now and these items are still around.

If they will never have any use, why not just remove them?
