This is mostly a gripe about weapon use In challenging activities. You are forced into specialized builds and weapons because of the champions. For instance this week vow should be a great choice for someone willing to use it and waste a slot for it. But it doest work with mods because it's only real use is that it stuns barriers. That's its only real exotic perk. In any way how does this make that weapon overpowering? It's got limited ammo slow fire and frankly a useless perk. Exotics are exotic for a reason and shouldn't be nerfed because of simple yet idiotic things like well we don't want one gun to stun too much.
