I was just thinking that maybe Rep Power would be better if it was like a rank rather than just a number, similar to the PVP rankings in WoW, not the same though obviously :P Like, with no rep you are a private, with 1 rep a sergeant or something like that.
If you did do this, make it 'easier' to get rep levels so people actually would get to the higher ranks rather than being stuck on 1 or 2 like almost everyone is.
