Just stop, you guys sound like *******es with all the "clickers" and "keyboard turners" complaining, some of the best pvpers in any game anywhere that I've ever known use that configuration. It all depends on the player.
None of the "best" pvpers are clickers or keyboard turners. The "best" duelists and such aren't the best pvpers. No offense intended, but keybinding is just better. If you aren't doing anything serious or don't care though do whatever floats your boat.
