It isn't Warcraft without Orcs. They're the center of the entertainment and drama.Horde always had more pride, mostly by blizzard themselves. They've never had massive pride for alliance. It's always been FOR THE HORDE!!! THRALL!!!! and nothing is every done or said about alliance. Love it or hate it, horde has had more lore development in the game then alliance. Thrall has had more attention then any other character in the entire history of warcraft. The next expansion is another horde expansion. Look at all the info, look at the name, warlords of draenor isn't a term for draenei that's for damn sure. Most alliance leaders have sat around doing nothing for eternity, like the night elves. Other leaders have had things happen but in the sidelines in books, like the tauren and the dwarves equal in that aspect. However Alliance has had more leaders completely non-existent then horde both gnomes and night elves have had literally zero attention in game. You wonder why alliance has no pride, it's because alliance are treated as joke races and a beginner faction.
