Thanks Alkyon! Updated the guide.
Also, I realized that I must have been wrong about the Supremacy/Harmony, Supremacy/Purity, and Purity/Supremacy, Purity/Harmony unlocks. The Harmony hybrid affinities unlocked for me when I reached level 7/level 4 of the affinities, but that didn't happen for the other hybrids.
Anyone know what unlocks the other hybrid affinities?
For me it was 9/3 for the other affinities?
Anyways, I now have everything but Pioneers. I think I'm going to take a break from Starships until someone figures that out.
