The best quote I've heard about the PvP is that it's like a fight between superheroes.
They just need to nerf Batman and Superman a bit and it'll be balanced.
That could have been myself, I've said it a couple of times here and there and stand by it. Whilst I am an AR/Shotgun user, I don't see a problem with minor adjustments. Along with the upcoming Scout Rifle boost, it should help keep things in just the right level of check.
