Well, when it comes to "Horde Bias" I don't think of it as the Alliance being at a physical disadvantage. Rather I think of it in terms of questing and story design. For one thing, the Horde has a war on with the Alliance which Alliance players simply haven't been invited to. WOLK and Cataclysm tended to look like the Horde story had the most emphasis while the Alliance had more of a hastily pieced together story as to what they were doing in the zone and then stops.


It feels like the Alliance slogan is, "Hi, we're not in right now. Please leave a message and we'll get back to you."

Also, the Alliance characters seem to lack depth. Garrosh is hated by a lot of Horde commentors here I know, but he tends to seem well developed compared to Varian. It's as if Blizz decided, "Hey, we need a counterpart to Garrosh" and made a one dimensional Alliance leader.

If you want more depth to Varian, you need to go to other sources as the game doesn't show it. Now we have some interesting villainous characters like Ambassador Grimes, but his role stops after 3 quests. There is never any followup to investigate his actions for example.

So really, if Blizz wants to overcome the label of "Horde Bias" they could go a long way by finding people to write quests who liked Alliance and cared about giving a good story with strong characters -- whether being heroic champions or by overcoming corruption within the Alliance
