What you're trying to say can only go so far. There's some people out there who might wanna use a certain weapon, but because there's something that everyone else is using that's way more useful than the weapon they want to use, they simply can't use it. They're forced to use the other gun because of how overpowered it might be or how underpowered the weapon they want to use might be. This isn't really much of a problem in PvE because it encourages using the best gear. But, although nothing's really overpowered in PvP at the moment, a weapon being overpowered in PvP causes the most problems. Personally, I think all the nerf calls are just unnecessary right now and Bungie's done a good job with balancing everything in PvP (even though it took forever for them to do).
