Luthien & Galadriel

[Gorthaur the Cruel]

Are you forgetting that Luthien actually bested Finrod's claim not long after. She had Sauron by the throat, and if she hadn't been as kind-hearted as she was, there would never have been a Ring for Frodo to destroy...

And are you forgetting that she had Sauron by the throat only because she had Huan at her side. It was Huan who couldn't be bested by prophecy. Morgoth was a dumb *** & allowed his lust to cloud his judgement. Sauron on the other hand was more cunning than his master & recognized Luthien for what she is. Had Huan been absent, Sauron would've slapped her silly. She may have sent Morgoth to lala land but that was a careless invite on his part.
Galadriel may not have done something dramatic as she had but she was someone to be reckoned with. Tolkien, again described her as the "greatest of elven women". Sure Luthien injected a divine substance to men but it continued only because of Galadriel who gave birth to Celebrian who in turn gave birth to Evenstar who chose a similar fate to Luthien. I'm not suggesting that she's greater than her, but perhaps atleast on the same league. And how can the elves be diminished in mind & body when the Three Elven rings brought healing & halt of weariness? It's even more absurd to say that the weilders themselves have been more diminished because they longed for the sea. Only Galadriel had this longing & in no way did it affect her native might. Perhaps, by the power of Nenya, she foresaw the fall of Sauron only by the means that she must give up her ring of power & this made all the more enthused to go home.
