+1, but -1
I would absolutely love to see more imaginative mounts being added in the near future, and wouldn't be amiss to having new sleds, carpets, clouds, etc.
That being said, those specific mount designs should only come back if they have been changed pretty majorly. I'm talkin' like a cloud mount where the player is angled 45 degrees forward, completely wrapped in a cloud, with wisps of cloud flying out the back. Or flying carpets where the user is sitting, with more flappyness on the edges (unlike the hovering that the old carpets have).
Even better would be if completely new and original mounts were released. Stuff like riding a tree (think sitting in the branches of Dryad charms), or sitting cross legged in the center of a large glowing wisp, maybe a new upgrade to heroic boots of speed that are more like a 90% boost that leave flames in your path, etc.
Please bring some more imagination in! The token system is great, but is still a somewhat frustrating pain for most players, a lot of people simply prefer to use old mounts because dying with a battle mount is such an issue.
I do realize that mounts take time to design and create, but I think they would be a good benefit...maybe for next event, take a pass on a new premium pet or new battle mount and do a really cool (gold purchased) shop mount instead? Please
