So many people state "there can't be horses in GW2 because they don't exist" Yet Centaurs do which is horse enough along with a whole line of other mounts that don't exist yet they are in the game (Warclaw, Roadrunner, Armadillo, sacred Pegasus etc which I won't go there...) . It's a fantasy game & they can actually make the rules what you wish, so why not bring in a set of various horses, heck even a camel which would work in Amnoon.. Give them abilities if you must & I LOVE underwater mounts Idea. .
