Why do you think it's a comparison? I already stated it wasn't. The statement isn't about who is more popular or shows up more, it's about what story they're tied to. Anduin, Jaina, and Genn are the Alliance equivalent to Sylvanas, Nathanos, and Baine. All 6 are the main ones involved with the main faction war storyline, with all the other faction characters being supporting roles to their wishes, intentions, and actions. Saurfang's main role in the story is part of an internalized conflict side plot. The closest we had to that on the Alliance was Tyrande. If you want to compare actions, you could make the same argument for the entirely of the Alliance since almost everything they've done has been reactionary. But since that's not the purpose of my statement, I don't plan on going there.
