The WAR Herald has introduced Realm Population Bonuses ! I'm always happy to receive rewards when accomplishing a great battle against the enemy realm, so the more the merrier!:

We are pleased to introduce Realm Population Bonuses. These bonuses are temporary boosts to help new players get into the game and strengthen their allies’ efforts on servers where their realm struggles to keep up with the growing armies of their enemy.

To view the current realm population bonuses, click on the "More..." link below.  We've also setup a post in our forums for the bonuses that we'll be updating on a regular basis.
