Less whining, more playing.
Geez, get over it. "OMG THEY USE BACKSTAB WHORE!" If backstab is so easy to avoid/counter, then do it and kill your opponent. Who cares if they run into battle backwards? Easy kill for you, right? A rocket up the bum, push/pull etc etc.
If you want to play "honorably", make a mod or your own server where all you can use is the light stance and you can only swing whilst standing still and connecting only takes off 1% life. Then you'll have your "honor".
Meanwhile I'll be having fun on normal servers using grip, backstab, rockets, and whatever else Raven put in the game for players to employ as winning tactics.
