[Raynor]

I am surprised to see that no one mentioned Feanor. I wonder if this is due to the fact that he doesn't come out as a favorite character for everyone, to be polite. However, he is described as the "mightiest of the Noldor", or, more generally, "mightiest in all parts of body and mind, in valour, in endurance, in beauty, in understanding, in skill, in strength and in subtlety alike, of all the Children of Iluvatar". True enough, we ought to take into consideration that he is not the brightest commander ever.
