User blog comment:Subject 9/Reapers intrest in Humans/@comment-74.178.168.199-20120716104727

I remember while fighting on ME2 on horizon on my insanity run I was hiding and trying to pickoff the collectors until harbringer came and said something interesting about the Krogan he said Krogan would have been potential if they weren't sterilized, then i got shot and was killed. That made me think about Saren and curing the Genophage if saren cured the Genophage, they were not breeding an army of krogan they were making a reaper. maybe we wouldn't have faught a giant human reaper, instead we would have faught a Krogan reaper. Which answers your question the reapers don't care about technology they care about the Genes of the species because the Krogan are definately not as advance as both those species.

look up harbinger qoutes under sqaud mates you'll understand
