Making players able to run faster with no penalty or stamina limits is not a good solution. Earlier BF games had way more vehicles (land, sea and air) to let people get around. 2042 has very few and actually less than launch with the nerfs. But it is apparently easier to speed up the walking simulator than sort out the balancing issues and actually get more vehicles in game.
I don't think the movement speed is such an issue.
Ground-based movement across the map is pretty predictable, but people flying half way across the map (wingsuits) or being able to get to high places instantly are way worse (zip-lines) and make the gameplay more casual/stupid than needed.
