Everyone's so tired of the war between the Alliance and the Horde, everyone knows peace is possible, everyone wants it. The people of Azeroth are tired of suffering because of their oligarchs nursing old grudges, and Anduin coming to power as king gives some hope for peace but others are cynical and believe that the cycle of violence will continue, as he's just another Wrynn on a throne built on the backs the people, another leader just waiting to go Garrosh or Greymane.
Confirmed. Morale gets quite low when you’re at war all the time. Completely avoidable and pointless war.
