what do you mean with that? i'm not flaming you btw or anything but when i'm there i can only use the wvw mount anyway so i thought because is in mist wars area you can't use the rest (if you mean that). or you mean the skin? Your default mount (the one listed on the screen, if you just hit your 'mount hotkey') gets overwritten with the Warclaw. I don't know what all triggers it, but if you log out in Armistice Bastion on that character, then log back in. Go to a PvE zone, and if you had, say, the Jackal as your default mount, it's now the Warclaw.
