Because that is NOT 40k, Chaos will always be the big threat no matter what else u throw at the milky way and unlike the Imperium or Serathi, Chaos spans the entire universe, it is enpowered just by the existance of sentient life. That and the blood shed caused by the Serathi mean that the Dark Gods aren't just going to sit on the sidelines, you can't make Chaos a small threat without destroying the character of 40k, Chaos defines the warhammer universe more than even the Imperium..
