Because hoofing it, at a slow pace, through content one has seen multiple times is tedious. The pros and cons are quite obvious. I picked up the game a day or so ago and my first thought was how arduous movement is.
I suspect that will be true for players making repeated trips through the same areas no matter what the running speed is set at. It will never be fast enough until people can click on a point on the map and appear there; someone will always want to get where they want to be faster than they can. At some point the developers settle on a speed (preferably one that doesn't look comical), and the speed we have currently happens to be it.
I don't have a "bone to pick" with anyone, but I do have a thing against changing a run speed that has been working well for others, and all for folks who can't offer a better reason beyond
"it's what I want" - people who are insisting this needs to change yet probably haven't even tried picking up the movement talent or investing points in the Speed attribute. You can make your movement faster.. the game has that option for you.
