What are the best ways to make the Alliance more popular and interesting?

[Mardux]

Figure out what makes the Horde more popular/interesting and then copy some of that.

For example it could be the rampant war crimes, genocide, bombings or exterminating your own allies.
Maybe it's due to the seemingly sanctioned botting, exploiting and rampant cheating that predominantly happens on that side.
It could also be the griefing, camp spawning and spitting during pvp encounters that makes them feel more cool.
Or we need more edge lord races compared the incredible vanilla flavored Alliance ones.

Well clearly those can't be it since Alliance already has those things going for it.

They should really try to significantly update some of the older zones, such as Ashenvale and Quel'Thalas....that would make returning players much more engaged. Most players probably don't even know whether most of Ashenvale is Alliance or Horde territory at this point, it's just very confusing.

I'm sure Blizzard doesn't know either.
