I am all for mounts, but i think they should be accessible at a higher level. (maybe 55 or 60). I can see it being very enjoyable if one is doing an event where you have to fight through someones base and you charge in on your black steed. Plus i think if GW2 gets mounts, then more skills could be unlocked giving the user more variety with his skills and how he fights. And I dont see it being a problem if you have to get them in the gem store either.
