I can understand where you are coming from. That we have a vast amount of mounts.. so why would they bother to think it would be a real incentive for players. This is why I pretty much nowadays just farm ones I find
interesting , unique, or enjoy in general. There is probably some hardcore collectors out there still tho.
Personally I like seeing all the
designs they manage to come up with there. Even if sometimes we get recycled skeletons, it is a
whole new skin.
(I get more people get excited about new skeletons and animations tho. It's pretty nice when they do this.) Still some of these creations.. I feel can potentially inspire other individuals.
This might just be me, but when I saw it. I thought of the World of Warcraft mount instantly.
So
personally I do still get excited about mounts and transmogs for weapons, armors etc. Critters, baddies, bosses, NPCs, in general etc. (environment too) It is just a bit of a downer when it feels like other departments don't come off as strong. For all we know they are not able to do the stuff they really want anyways..
(I picked up a couple new mounts this
current patch)
