The whole balance thing is so stupid imo. I would love it if one of the factions was considerably inferior for an entire expansion, it would allow for much more interesting storylines. Right now, everything feels the same. Same number of cities, pretty much same forces, same number of races, and nobody will ever gain the upper hand due to gameplay reasons. As an Alliance player, I would LOVE to play some sort of a rebelion faction - let the horde destroy SW and the other cities, make it a war that the horde wins and Alliance are surviving in hiding and little villages. The possibilites for interesting quest chains would have been endless. Horde quest chains to find the remianings of the Alliance and destroy them, and Alliance quests to get resources and sabotage horde bases here and there to buy some time. Let the power shift between the two factions over time with actual in-game results to the quests, I'd love to see that.
Instead, what Blizz has made is making the Alliance look silly. MoP was supposed to be all about the war, but where was the war in the game? I kept looking for it. The Ally first quest of the expansion looked so promising, so war-like (not sure about horde), but then it was all Panda, Mogu, Mogus, Klaxxi, more Mogu, trolls, Mogu, and some Mogu. Patch 5.1 showed bits of the war, but very little of it. I understand its tough to display a full scale war in gameplay, but something? Meh.
Anyway, I just hope Varian's there when Garrosh dies. This has been due since the Ulduar patch trailer.
