Actually the problem is this: Balancing guns differntly in PVE and PVP will change how they feel and function to the point that it will prevent people bouncing back and forth between the two. Everything Bungie is doing is based on making us play both pve and pvp. (and making us create press gangs to force our reluctant friends to play....) The better way to solve this problem is to tune down mob damage resistance in PVE. That way the guns still move the same and feel the same in both pve and pvp, but are still more effective in pve. Of course, simply having more that two strike dificulties would help, lvl 41 is BS for casual players.
