While I enjoy reading about the WoW lore, it may surprise some people to know that I'm not a big fan of the books. A great deal of my indifference is due to the design decision in Azerothian lore to emphasize the leaders at the forefront of everything.
Look at it this way: if you're out questing in the L1-L60 areas of Azeroth, when you report to a faction leader, it is a "big deal". Sure, you can show up at any of the capitals, walk right up, and dance around Sylvanas*, but actual interaction with the story is fairly rare. The emphasis, naturally, is on you as the hero. You're out in the field, interacting with people who report up the chain to the faction leaders. Now, there are third party groups out there you interact with, such as the Cenarion Circle and the Argent Crusade, but the lion's share of quests come from the two factions.
This format makes sense, because the faction leaders are consumed with less of the day-to-day and more nation building and maintenance. There are advisors and councils who deal with other things, such as the war effort.
Historically, by the time we reached the Age of Enlightenment it was a rare sight to see a monarch in battle, and a monarch having adventures was unheard of. Monarchs weren't the strongest, most powerful, or most intelligent people in the nation, but their bureaucracies ensured that they didn't need to be.
Azeroth, on the other hand, has a bizarre environment. In the time of WoW, Azeroth has lost a great deal of its population, but at the same time has tons of toons when a server is busy. There are Native American inspired cultures and "the strongest rules" medieval type of societies, but also has the trappings of Steampunk and the later Victorian Era. These are huge continents, but near instantaneous travel via portals is a reality. And yet the societies don't have any cross pollination, despite the forces at work.
This is a world where --if you follow the books and the lore-- you have the faction leaders and their equivalents going off on adventures. They are the focal points, because they are the strongest, the most powerful, the most intelligent. In some respects, this is a lot like a David Eddings series.
And like a David Eddings series, after a while it starts to feel like a who's who of people at the top. The rest of the Azerothians don't exist, except as a bunch of red shirts.
I suppose I can't blame the books, given that the authors are working within Blizzard's constraints, but it just doesn't feel right. WoW has taken the focus of the game away from the folks at the top and given it to us, yet the books are still stuck in Warcraft 3 mode.
*Not to mention the inevitable question why you'd do such a thing. Unless you have a death wish or something.
