After an abysmal expansion based around the adventures of a unstoppable Orc Shaman and Night Elves being slaves to the ever wonderful green skinned Neanderthals, Chris Metzen promised us in MoP the Alliance will see development again. All lies.
The Horde destroys Theramore, and rather than seeking vengeance, our beloved archmage shrugs it off and goes neutral. The Horde kills all of our troops on sea with no casualties, while being led by a totally new character of Nazgrel. The Alliance is led by a coward that hid and let all his troops die, to further please the Horde fans.
No Alliance ass kicking or development at all as of now. Bravo Blizzard!
So while Blizzard was glorifying the Horde in Cataclysm and MoP, what have we done that's cool?
We destroyed a camp of Tauren and even offered them escape, and the Horde playerbase screamed and threatened Blizzard with subscription withdrawals. Since then, no Alliance glory or development whatsoever.
Just getting killed by Horde like pigs to the slaughter to appease the crowd.
