I don't know, there are fewer and fewer actual night elves by how we met them in WC3, and funny enough, one night elf whom I could say for sure "this is a night elf" was Thisalee Crow, which was neutral. I felt she was how night elves should be, as in, faking not being interested in anything(she was cleaning her nails with a dagger when she met you), watchful of others (though she sent you to deal with the harpy leader, she was there too, she was watching you), smart and devious (making you think you have the choice in dealing with the harpy, but she has the blade) and savage (if you chose to let the harpy go she says she probably wouldn't have done it).
Another night elf that actually is in the Alliance is Shandris. She kind of has same aspects, doesn't let anything to chance, has experience etc, I won't go into detail.
Yet that's how many, 2 night elves and 2 zones? What about all the other places night elves are in? Ashenvale just makes me sad seeing how low the night elves go there, how stupid and incompetent they are, Azshara the same, I won't even speak about other zones.
