Some people really want to create a political shakeup (and have the power to do so) however it is VERY risky when the norm is no political change for half-a-decade. While perfect assurance isn't needed, it is nice to have at least some idea that something might work.
Another problem is that internal "not caring" about things has also affected a few realms who could have changed things up from what my intel says.
Also, more than any other continent, Atamara is still pretty heavily influenced by the "team play" idea which makes shaking things up particularly difficult sometimes.
