It gives you an unfair speed advantage, makes you jump alot further and makes you much harder to hit. Pretty sure that's considered Unsportsmanlike Conduct by it's very definition. We are more like a Gaming Community and not a Competitive Gaming clan.
Rapid Fire binds and Pro Mod Configs and Jump Mod binds all give an unfair advantage to everyone else playing on the servers. And crap like that tends to piss people off and empties the servers.
Just play the damned game. If ya can't play without some sort bullshit cheat or modded config or fancy binds to get an advantage maybe you should find another server or game to play.
