The two races, the Insect Race and the Green Skins, due to their characteristics, only grow stronger the more they fight. Especially after such a grand decisive battle concludes, the victor becomes exceptionally powerful.
But on one hand, this strength needs a bit of time. The Insect Race needs time to digest their 'spoils of war.' So many living or dead Green Skins must be consumed, then digested, and then hatched.
This requires time.
The Green Skins are the same. After victory, the so-called 'waaagh' field promptly feeds back to them, making them immediately stronger. However, the numbers they lost in the brutal war still need to be replenished one by one by the 'mushroom plantations,' and this replenishing speed is slower compared to the Insect Race, with more limitations.
