Comments of chapter undefined of Transmigrated as Talion in Middle Earth - hiatus waiting for rewrite

I may be wrong, but Sauron was stronger before the fall of Numenor than in LotR, because for survival he sacrificed not only the ability to change shape, but also the physical form, which according to the description was beautiful as the best representatives of the elves. In general, the level of forces in the professor's universe is very heterogeneous, for example, the Balrog who killed ALL the dwarves of Moria is obviously weaker than Sauron, but Sauron lost in a duel to Isildur who could not defeat Barlog.
