[SUGGESTION] Implementing walking?

Would implementing walking(faster than crouch but you make no noise) be difficult? Would be a nice feature in duels i think since when you crouch you go really really slow.

I'm not saying I'm for this option or against it (no preference) but: Instead of walking, then making the crouch just a little faster would be a better option. As the biggest reason anyone crouches is to dull out the footsteps sound. If walking were to be implemented I don't see people crouch anymore. Also, it would be a bit redundant having both.
