Something has changed with the armory recently, and the count for collected mounts does not reflect the in-game amount any more. This is due to some retired mounts, ie. Swift Zulian Tiger, Razzashi Raptor, Swift Zhevra, to not appear on the collected tab any more.
What is worse, is there are dozens of mounts on the not collected tab that -do not exist in game- (ie ones that existed in beta, and never made it live) AND ones that ARE retired and cannot be collected (Old Gladiator mounts for example) AND ones that you can't get (ie class specific mounts, other pandaren phoenixes since you can only get one color per char).
Could we please get some consistancy.
