Honestly I can't see how there should be anything unfair in hide mount.
If people feel cheated/beaten by someone who does it, they can do it themselves also, it would afterall be a choice for everyone..
Its much like the cloaks and helmets, some like the look, some hate it, and we now have a chance to hide both.
Next step would for sure be the mount, I know the only reason I dont have one on ANY of my toons is strictly because I hate the way it looks..
Was also why I asked, because I know there are many people who feel just like I do
