And about Tuor killing Balrogs- the ones he killed were watered down versions of what most people think of when they see "Balrog" (they think of LOTR Durin's Bane). Back when Tolkien wrote that about Tuor there were bunches of Balrogs. Later he made them fewer and more powerful.

Please quote from source of said information.

Well, I'm not at home with my books right now, and even if I was it might take me an eternity to find. All I know is that in his earlier drafts of stories, there were "armies" and "hosts" of balrogs, and that they were slain by all sorts of elves. In later stories, the balrogs appear to be much more powerful. For instance, the balrog that Gandalf fought.

I know for sure that, someplace in one of his drafts, Tolkien wrote a note that there were, at the most, seven balrogs. This is an obvious change from his earlier stories, like his early version of the Fall of Gondolin (the one where Tuor kills multiple balrogs).
