O sorry if i misunderstood you, the new gear in Celestia will probably be actionable for the most part aside from some rare boss drops and the level 60 gear. The level 50 stuff from dragonspyre will however, remain no auction.
Did you ever notice Shop gear has a lot of Hit points. I do not think Shop gear should be like it is already. I think Shop gear should have Accuracy, Deffence, and Hit bonuses on it, Like a higher percent on the gear then what the game offers.
I say make shop gear auctionable and drop gear non auctionable, only because drop gear is harder to get. I also feel there should be worth wild bonus's on Shop gear then just the more hit points buff.
