Jeez... Sure, make a khopesh like a longsword with a trip ability. Then laugh while half or more of the player base leaves the game (This would be such a nerf, worse then any nerf turbine has done including Evasion in heavy armor). Why would so much people leave the game? Because most players have at least 1 or more characters that uses Khopesh. They put a feat into it and crafted 1 or several shroud khopesh for their characters. Forcing them to respect a feat and recraft their swords because it's now just a plain old longsword (BTW trip is useless on raid or red named bosses, and that the only place you really want DPS) would be causing such grief. If your not done laughing, then just keep on laughing while you see the other half start grinding shroud again and eventually get bored and leave. BTW half the population leaving the game means you are in trouble, because it means the game will be in trouble financially - thus less developpement, less support.
I agree that currently, Bastard swords are the only exotic weapon where you spend a feat but get very little in return. It should be looked at to make available for 1h wielding OR 2h wielding. That is what a bastard sword is all about
