Well, didn't Bungie even mention that I've Breaker and Invective would still work against the Special ammo nerf? So I don't see it as cheating; I see it as using an item in the game. Again, I think people are saying it's an exploit because it's effective. People have used these two guns to regenerate special ammo and switch to another gun since they came out, so I don't see what the problem is.
