How can they adapt when they can be wiped out by a literal fraction of either the Imperium's of Forerunner's forces? You keep saying s*** about them adapting but that would mean they have to win a single battle. When the only thing they have is indoctrination, which can be easily detected by the Imperium or Eucume, they're pretty much screwed in every single scenario ever. The only reason the Flood defeated the Forerunners is because of their biology. Unlike the Reapers, the flood can spread rather quickly all the while adding the enemies forces to their own. The Reapers can't do that because they simply too weak to defeat anything save for stragglers which either side can easily send a small force that would wipe out any and all Reaper forces in a millisecond. The Reapers don't have time on their side. As soon as either side discovers them, it takes only a wave of their hand to be destroyed. The Reapers simply can't fundamentally adapt ALL of their freaking forces in that short amount of time.
