Well, there are people that don't want a more challenging game, those are the people that are satisfied getting easy kills and wins by the gun rather than acquiring and applying skill.

And that's the #1 reason this idea would be turned down; unfortunately for those of us that enjoy applying skill to the game, there's people out there that are afraid of losing the power to easily win.

To that, I say "easy come, easy go."

There's also the possibility that nay-sayers simply don't understand how changing the walk speed will improve the gameplay or make it more challenging. These people with this lack of understanding likely haven't tried the medium-speed spar, and are standing strong with the consensus "if it isn't broke, don't break it".
