I don't have Fatebringer, but I understand your generalizations here. The reason people don't want to give it up is the exact reason that I already stated. There's just nothing that compares in most people's eyes. The stats + the aesthetics of the other weapons just don't add up to something people consider comparable. I have no problem with what's going on, but I'm also not going to downplay the validity of civilized argument. People on both sides are making a valid argument in varying cases, but it's the blind extremism with/against Bungie that drowns out these rational voices.
