That was a fantastic, and meaningful, addition to this conversation.
Anyway, back to the topic at hand. There's a part of every MMO, Tabletop RPG, or the like That makes you glad you chose the race/faction that you did. Be it a key moment in the story or some kind of "nifty" racial ability, there's a point where you say "Yeah. I made a great decision."
For me the thought was always there, but the overall culminating moment was a quest chain that ends in Dragonblight and has to do with the Taunka's inclusion into the Horde. It just kind of summed up everything I think is superior about the Horde, given the circumstances of the Taunka's inclusion. From a lore standpoint, the Alliance (with the exception of the dwarves) just seems to me to have the mindset of "We're only going to be friends for now because you have something we need. Once that goal is accomplished, you're out the damn door." Whereas the Horde mentality (again, strictly lore-wise) is more along the lines of "So your society and people were nearly wiped out, right? Join us and we'll help you rebuild to your former glory. And even after the goals are accomplished we can still hang out and go fishing or something."
