I'm leveling a lot of alts. (I just like making pretty charactersa lot, can't waste having made them). That means I know awfully well how annoying it is to have this huge sprint cooldown on you. You can teleport in cities. After unlocking the aetherytes. You can use mounts. After level 20, when you're not in a city. And some things you can't use aetherytes or mounts for (read: Miounne, and running between her and whatever other place constantly).
Hell, you don't even have to be new. Just gather. sure you can mount up all the time but it's not the best experience. Do anything where you have to run between to people multiple times. Supply leves, the people don't stand right at the aetheryte but you can't sprint in cities. Or just have slow internet, so going from point a to point b on a city map is still faster than teleporting.
It would do literally no harm to anyone to at least make sprint a little better. The only reason speaking against it is "Well I can use mounts and I don't do anything I'd have to use sprint for, so you're just out of luck".
