Enough races. The Alliance and Horde are basically nonsensical factions now. The Forsaken basically is off doing its own thing, Trolls/Tauren are combined against Orcs, Blood Elves doing whatever. The Humans are the lead for Alliance (as usual), with all the other factions being more or less just their lackeys to the point where beyond Night Elves, it feels like they could just make every damn race (including orcs) a human boot-licker with how little the other Alliance races matter.
