Shouldn't knights of Dol Amroth have dwarven strength armor? I know what you will say, how can men hope to get dwarven armor when the elves don't have it but tbh Black Uruks have it and I know Sauron is a maia and he was trained but Aule the smith but Sauron can't even take a form and Orcish armor is shit: I know they are actually good at crafting but they massproduce more than a Soviet tank factory in 1943. And the orcs/easterlings shouldn't be able to dream about matching a Gondorian soldier. They don't have numenorean blood but still they are exceptionally trained and have pretty good weapons/armor. Also, what about the damn levies? What are they supposed to be? Gondor has them but Mordor/near Harad doesn't have a weak unit?
Actually, Sauron did have a physical form in the events of the LotR. I know PJ's trilogy just sets him up as a flaming eyeball, but he did have a form and stuff. Gollum mentions that, during his interrogation at the Lugburz, Sauron himself participated. Gollum also mentionned that Sauron was missing one finger, which is the one that Isildur cut off during the War of the Last Alliance.
