The Gods are cleaning the battlefield here, while within the major planes, the situation has reached a boiling point.
Gods cannot casually enter the planes because their strength is too destructive to the planes.
Another reason is that the otherworld has a strong repulsion to foreign Gods. Even if they do nothing, once they enter, they will be repelled by the World Power, which is a very normal situation.
With their current actions, once they enter, the World Power would attack them.
This kind of attack mostly manifests as a natural disaster, and if the Gods want to resist, they can only cause damage to the world.
Moreover, these attacks are evolved from the World Origin, and at this time, the World Will would not hesitate to use its own origin. The more attacks there are, the more consumption there is, and the less benefit they receive.
This is why these Gods are unwilling to enter the planes and instead only allow those below Gods to enter.
