Well honestly, talking deathclaws could've worked if executed differently. Although, I think Goris being the last of his kind makes him even more unique, he's a scholar which is rare in the wasteland, and he's a an albino deathclaw which is also rare, then you remember he's a talking talking deathclaw and he uses a robe to blend in with humans, making him really unique. The next way to make him more unique would be to make him the entire population of a species, the intelligent deathclaw species.
I do think that the bug where Xarn never warns the vault 13 deathclaws of the Enclave finding them out should've been fixed. However, I agree with Atomic Postman on this:
I still like Goris as well, but maybe he could've been the deathclaw being held captive at Navarro. Goris could've been the first deathclaw to be apart of the deathclaw FEV experiments, the FEV turns him albino, allows him to parrot human speech, and gives him sentience. He's going to be euthanized because he's just a test product, but if you help him escape then he will meet you outside Navarro, after killing the guy who directs the new Enclave recruits to Navarro and taking his robes. He will ask to join you because he doesn't know what's out there.
A possible ending for Goris is that he becomes Arroyo's official scholar. The reason he would choose to join Arroyo would be that he doesn't want to leave the Chosen One's side, because Goris still has mental age of a 4 year old and the Chosen would be the only parental-type figure Goris can remember.
Maybe, just maybe... Goris convinces a female deathclaw to join Arroyo, and there is then a very linear line of intelligent deathclaws that don't leave the tribe ever. Maybe one leaves the tribe but doesn't reproduce outside of it.
Are these good middle grounds for everyone to agree on?
