The alliance is more tightly nit than it EVER fucking has been.
Meanwhile the horde is crumbling on it's rusty old decayed pipes
Baine hates Garrosh, Vol'jin plans to KILL Garrosh, Sylvanas just does not give a shit about anything and uses the horde for her own motives. There are not many but even some Orcs hate Garrosh and I am not sure about the goblins but...whew, That sounds like a stable faction to me.
Meanwhile the Alliance is strengthening bonds and working together. Yeah. Just no.
