Agreed. Moving the camera with WSAD is a total waste of both Classic and GridKey hand positioning.
It would mean your hand is in a position that would need to move abnormally to reach the very hotkeys that speed up your gameplay.
If WASD always match to Up Down Left Right arrow keys, yes, your hand will need to move abnormally but if you use a "shift key" to activate WASD as Up Down Left Right arrow keys just when its key is down your hand position will be normal.
I also agreed to the fact that moving camera with mini map is mostly faster than WASD. I use WASD because it's easier to use and require less mouse gesture.
