Personally I would like to see in the "closet" what each mount does. If I had known that were-bear was so animated for the Warclaw I would of DEFINITELY bought it.
Recently got out of the VA hospital, and trying to adjust back into the game, and picked up on WvW again a day after the were-bear vanished. That one mount if sooo animated, and noisy, I so would like to see it back again -- soon please. Got the Geode mount instead. It's cute, but that were-bear would of been awesome to have on both my accounts. :)
If when clicking the new mounts for preview, if they would show their special animations that would be a bigger sales point. Most would probably think it was the same old animated mount. Since playing WvW last few days I been seeing these things rare up on their hind legs! Yeah, I would of bought them if I knew what their special animations did.
