Go into any PvP game and count the number of autos in play. People use them b/c they're OP. I make it a point not to play with an auto and my pulse/scout is a rarity in PvP, especially since Bungie made the idiotic decision to reduce the weighting for the only 2 medium-large maps in the game so they hardly appear in the rotation. If it's difficult balancing weapons then it just makes Bungie look more incompetent for not addressing this before the release.
