I think I see where you're coming from, but I don't think I agree. First of all, I don't really see why adding mounts is a bad thing if the point is to not feel constrained by travel time. Running will always feel slow to me because faster modes of transportation are commonplace - not just in MMOs but in life (horses, cars, bikes, etc). Even if we had the equivalent of waypoints irl, I'd still prefer to bike to a nearby location rather than walk. But I wouldn't take a jet from my house to my work that's only 5 miles away, just like I didn't hop on my epic flyer to go from the bank to the AH in WoW. For that commute I would simply run. As another example, if I was touring Yellowstone for the first time, wouldn't want to walk across the entire thing but I also wouldn't want to teleport to just a few locations. I would prefer to drive (or more accurately, I would prefer someone to drive me) with a few stops along the way to walk around.
