Bu--bu--but... but the Warchief always gets to be a faction leader! This is too confusing. Just make Sylvanas:

Illuminated Warlady of the Horde
Honorary Warchief of the Orcs (by virtue of leading the Horde)
Banshee Queen of the Forsaken
Eternal Queen of Quel'thalas
Most Evolved Queen of the Trolls (and descending trollish races)

Then she can play a card game against Gallywix, and shark him to become:

Official Owner of the Bilgewater Cartel


Then you just have the silly Tauren and some Pandaren to worry about. I'm not sure what the etiquette is there, if she can take over the tribes by challenging the racial leaders to single combat...


EDIT: I almost forgot her most important claim:

Supreme Commander of the Alliance of Lordaeron (by virtue of controlling Lordaeron, totally for truth reallies gaiz)
