[Thinlómien]

* I'm not sure if all the dragons should be above Sauron. At least I would put Smaug below him.
* The Witch King is placed far too high. If Gandalf could cope with all the nine the same time, he's definitely too high up. Besides he was killed by a human, who wasn't even a great war hero. Thirdly, the rangers were able to drive away the single nazguls. Fourthly he and his 8 fellow buddies were not a match for Aragorn and Glorfindel.

I'm rather interested where Aragorn should be placed on that list.

*I would drop Túrin far lower. He doesn't deserve to be so high up. Wasn't it said that Fëanor was the most powerful of the children of Ilúvatar?
*Shelob should be higher up. It is said about her that no war hero of ancient times could have vanquished her. Or wait... Something like that. I should probably check but I'm too lazy. At least she should be above trolls. I think you overvaluate trolls. Pippin slew one. Tom, Bert and William are surely dangerous, but not more dangerous than Shelob!
*Ang, I disagree about Fingolfin and Maedhros. I'm a fan of Maedhros, but I would put him below Fingolfin and them both below Fëanor. He was maybe a stupid guy, but he was a powerful genious.
*And I would place Gollum above an orc and spider over hobbit. Bilbo was an exceptional hobbit and he had an exceptional ring. An average hobbit is a plump farmer. I don't doubt that a spider is more powerful.

Where would you people place the Ring? That's an interesting question.
