We should spend twice as much energy to be able to run faster, at a shorter distance even.
It would make resting, mint cakes, stamina management and agility more impactful.
I also just find a faster running pace for commuting to be more enjoyable or more dynamic in long distance dangerous situations like wildy pvp chases.
Due to engine limitations, faster movement is not possible. This is one of the reasons why we have things like Surge and Bladed Dive to get around quicker.
