If the weapons are "too powerful" then argue for them to be removed (or not added, as it were). If they are added don't then tell us that letting someone choose a quarterstaff or bastard sword with the exact same properties as the khopesh or rapier is going to compound the problem without some argument better than they "are the way they come because that's the way that they come". You could just argue that you'd rather see Turbine spend time on something else rather than this but claiming it's problematic for the same set of properties to appear on a player's choice weapon base instead of only on a khopesh or a rapier is ridiculous.
