There is one real big problem with the alliance. Humans Run around doing shit while other races' leaders mostly do nothing at all, and when they are showed, its to be like: "Varian, im your bitch, use all my armies, forever yours. You were right, peace out"
Varian steals all the spotlight from everyone. Horde leaders in comparison are all accounted for in this expansion with appearances in either books or cutscenes.
Here is a small comparison:
-Varian: Every scenario has him in it, every alliance cutscene deals with him.
-Jaina: A major focus during this expansion is on her. No problem tough, she deserves it.
-Anduin: Same as his father mostly.
-Tyrande- Used as a support character for varian in a scenario in MoP, being completely out of character. Didn't do much else. Look up and you will see what she pretty much said.
-Malfurion- AFK ATM
-What gnomes? Who was their leader? Lor'themar mark 2? Not heard from at all.
-Genn Greymane. Played a minor role in his starting zone. After that everything went to town and his race became pets for night elves. AFK for the moment.
-Pretty much same as Tyrande.
-Velen: He is a prophet. Pretty much nothing else.
I find that highly Irriating. Blizzard wants to make every race in the Alliance a loyal lapdog for the humans. The Night Elves' Ferocity of old is gone. The Worgen, the supposed "savage alliance race" are nothing more but pets and druids. Dwarves are being pricks and are pretty much servant N1 of Varian.
The other alliance races never take any initiative, never do anything untill Varian tells them to. Booring, Characterless, alliance races. Sad.
