Also we need more than anti-Chaos stuff, right now we're not working to combat that. We saw the strong hints, of a race that can be a guide.

Magic Resistance
Lizardmen are fine for elites, especially since we have them a buff over the standard template, but when it comes to sheer numbers, none of our creatures have the ability to sustain casualties in the apocalypse to come. All warfare above a few hundred soldiers is going to become a war of strategic resources and attrition. Imagine it as a Total War army build: You always want a core line that can hold up on defense and push forward for attacks. And I say that's human, enhanced. Norscans were basically operating on crude iron, stone, bone, and furs, yet continued to terrorize nations that hit industrializing by virtue of being stronger, tougher, and fanatical.
We take that concept, and throw in a few strategic goodies: They're magic resistant, so Chaos will have to sword-and-board or rely on higher-tier magic assets to get ahead. They've got both Prolific and Queen, so we can plop them down just about everywhere and keep a grip on their culture while they turn into a near-instant army. We almost don't need to worry about lifespan. We'll have so many the generations will replace themselves and more. We'll also have heavily invested in their ability to grow anywhere, so we don't have to worry about fixed infrastructure being destroyed. If there's no war, we can make them an adaptable substitute. Large numbers for labor, paperwork, agriculture, etc.
At that point, we can then turn back to the specialized stuff and whatever magical goodies we want to stuff into an exotic chassis.
