You think bunnyhopping like phoon was is a feature? That was completely game breaking. Valve multiplayer games are built on balance and CS is all about balancing the timing of who gets where first. Being able to move that fast completely broke the mechanics of the maps (which is the whole point of the video). It allowed the guy to get in places people are expected to be but at speeds that completely ruin the balance.

These kinds of exploits don't increase the skill cap because you can't figure out how to do it while you're playing the guy whose exploiting. If some guy found a new spot to bounce nades off of, or a new place to peak, you can learn and reason about that and react after a few rounds. There's literally nothing you can do here unless you magically discover how to exploit a bug to move faster.
