Same without those major shipyards the Orks will have to rely on limited piracy as well as hinder there ability to get a proper WAAAGH! going. I can be convinced on medium which will take away some of there important strategic resources (whatever those are. I'm guessing Squigoths and Ork Mek worlds that make titans or something).
With the tech trades I would really like it if we refrained from giving anything too strong. I just know that these Blood Dragons at the individual level may become corrupted due to there Imperium like size which means valuable knowledge and equipment falling into enemy hands. Also doing these trades means giving up secrets that show us to be a technology power that may attract the Dark Mechanicus. Which is bad.
1. Again. Please let's just try to swap out Imperial Tech and Maybe some freebie Royal Basilisks in exchange for those Forges.
2. Followed by buying some merchant ships with thrones from Avernus's personal coffers and negotiating for lower prices because of the fact that were taking down there enemies that are tying up more than 4 thousand Space Marines and 30 billion guardsmen.
