Not as far as I know, I logged in yesterday and my 60 characters are still standing there in shinning armors and whatnot, they even gave me a new mount for being a founding member lol.
are you an US user ? or do the europeans also get the mount ? I thought it was only for paying costumers afaik (here in europe)
if not maybe I should dl and play it again. Played for 2 months, when it still was sub based. It was a pretty good game.
