Horde players often complain that the Alliance gets to be perfect and unified, while the Alliance often complains that the Horde gets more complex story development. Regardless of which side you agree with, I think it's fair to say that the Alliance should be given some conflict. That's the only way to make the stories of the interconnected Alliance races more interesting.
So. How do you think this should happen? Should the other Alliance races turn against the humans for being too politically and culturally dominating? Should the dwarves recede from the Alliance to the safety of their caverns? Should the Worgen raise hell for not being helped at all with Gilneas? Should the Gnomes turn against the Night Elves for rejecting technology in favour of the earth?
There are so many ways the Alliance could become more complex, but right now, it's all "Yo Varian is so perfect, isn't Varian perfect? We all love Varian and his perfect perfectness yay for us" - Paraphrased from Velen
