I've been here since the release of Crota. I remember the Thorn and its 2 headshot ways. But now we have another "Thorn" situaltion. It took Bungie and entire few months to fix it and i hope it isn't the same for the the Doctrine of Passing. Granted, I don't have it, but the people who do have it are ruling the Crucible right now. So personally, I think it should be nerfed and others are probrably saying the same thing.
