I don't like the idea. It would feel sluggish and sloppy, hard to hit with, and not at all rewarding. If you're talking about the basic melee system, you'd be ruining a great formula, and too much would become ping dependant. Not to mention, it would open up a great abusive gateway for _special scripts. Those are pretty much the only abuseable script in any HL mod, and currently ESF has nothing that could be abused by such.
