Almost 7 hours after I finished the ExoGalactic Transmitter, I am not sure if the Spire are going to be able to take the last homeword on their own. They keep dying in a combination to all the hunter killers that the AI spawns in each Exo waves and a Devourer Golem. And I am only playing it on 7/7. At first it looked like they would never get past the first homeworld, but after a while they cleared most of the map, but the last Homeworld seems to be too hard for them.
