[Boromir88]

I mean no disrespect to Tuor, but just showing how powerful Balrogs became later in Tolkien's writing, I highly doubt a single man could have killed one...let alone 8 of them. So the 'even' is for the fact that Tuor was a man, and in the earliest drafts a man killed 8 Balrogs, yet Balrogs were still more powerful than dragons. When Tolkien started changing his balrogs and made them Maiar, I would 'bet the farm' that a man could not have killed one, let alone 8.
