Heads up, I never played World of Warcraft and only have knowledge for Lord of the Rings cause of the movies
I did really like this episode. Despite a few issues.
I do like both rundowns. My favorite joke for Sauron's was that he was defeated by Elijah Wood and for Lich King's was defeated by 25 nerds on a server
I do feel like they focused on the Lord of the rings movies more so than any of the book versions of events
As for the fight
I liked it.
The reason for fighting makes sense, Sauron wants Lich King's powers for himself
The voice acting for Lich King and Sauron are really great.
The magic usage looked really good
Lich King trying to make Sauron his servant but failing was cool (reason for not working was in the analysis)
Sauron bleeding from the sword strike to his hand and immediately fighting off Lich King saying, I serve no one was cool(despite him serving that one character)
The frost Eye of Sauron from Lich King was cool, breaking Frostmorne(did I spell it right?) was a great touch
Sauron's final line before killing Lich King while appearing on Lich King's throne was great.
"There is no life in the void, only death"
Sauron destroys Lich King's body and soul(though the corpse just dropping kind of sucked)
Sauron wins
Next is Deku from My Hero Academia vs Asta from Black Clover
Just so you know, I hate Black Clover. So you already know who I want to win
