I understand where you're coming from. But I'm thinking bigger picture, beyond the weight of the players when running. It's a core change that needs to be corrected to improve the overall gameplay experience of all movements.
I've heard some say that playing on slower speeds gives it less of a skating/floaty feel.
Cosmetically, it may "feel" better, but like I said, I'm a proponent of fixing it at the core so that all action that results from that improvement will benefit from such an improvement.
