Not addressing your specific concern (because I am not the story or lore guy ), but a piece of LOTRO Trivia:
- the Gauredain were originally intended to be able to be skin changers when we introduced them WAY WAY back in Evendim. Unfortunately, at the time, we did not have the tech necessary to pull it off so instead they were introduced as a group of Wolf-worshippers.
I'm really glad that happened -- these wild men and beast cults would be among the more common humans on Arda at the time. My only problem with the Gauredain is not lore, but that they're too big.
