Reasoning
The reason behind wanting new AO's on King of the Hill is simple; playing the same AO's gets repetitive. Not only this, but because of the lack of AO's in the KotH game mode you sometimes experience the same AO every other game. However, with more AO's in the rotation the likelihood of this happening would be decreased, introducing more play-ability to the game mode and making it less stale in the long run.
Why is the priority so high? Because it's important that the game mode remains engaging for players. Although the KotH gamemode certainly is not dead, new maps would provide a breath of fresh air and most likely bring M.I.A players back into the action.
