One type of character one rarely sees in PvE is archers. This is mostly because a longsword is a lot easier to make and a lot quicker to learn. That and you're not constantly having to make more arrows... To balance this extra effort, in PvE (since bows in PvP are essential they already have a function there) why not buff the damage bows to do mobs in PvE? Something that means a player who spends the hours making the arrows actually has a use for them that doesn't involve killing other players.
