Epic mount quest? You arent talking about the SS carpet (free), Warg in LP (5p), the new carpet in LS (6p). So I really dont know what one you mean (Since the new mount doesnt come out until tomorrows patch). The only thing considered epic mounts (aside from those dropped in raids), are the ones that are available at city merchants, with the max being 42p and 750k status points. Speed wise they are the same as the new carpet, but the buffs on them are well worth it.
You could possibly be in the wrong forum, since I think WoW has epic mounts. I have no knowledge on behalf of that game however.
