No offence to anyone, but all those Chapter ideas are awful. Astartes are special units, that's what makes them useful to Imperium at all, considering the hilarious, number difference between Space Marines and every other force in the Imperium.
During Great Crusade when, thanks to Primarchs, Space Marines could be produced in significantly larger numbers, they still weren't the main military unit, Expedition Fleets which had Astartes accompanying them were privileged. Astartes served as spearhead for the actual army, Astartes dealt with all the very specific, big, threats while the actual army was taking care of the majority of campaigns and compliances across the Galaxy.
Astartes are special units, commandos, they win wars by killing the enemy leadership not by waging war like normal army. And Astartes aren't naturally genuises. They have potential to be very intelligent, far surpassing baseline Human, and can do stuff other than fighting, but that doesn't mean that they all are like that. Most Astartes aren't that significantly more intelligent than baseline Human.
So creating a entire Chapter, that doesn't nothing but heal people actually fighting on battlefield and cure plagues is awful idea and waste of resources or Chapter that has any influence over normal Imperial army and grows much larger than it should, which wouldn't go well politically and would most likely result in Chapter getting destroyed.
I think next trun we should use all our points to unlcok the rest of the trator legion geneseed we should have enough to do it next turn, and then take a mission that wont need alot of geneseed charges like the experiment mission where we put an alpha legion chapter on an ultramar world
Or, you know, don't take anything? We don't need to take any requests, we can just create Chapter because we want to create it.
Eh, racking up a t-legion or two at a time makes sense to me, but splurging for a whole ton at once doesn't seem like smart use of resources. Unless these are one time use deals?
Yes?! Did you read anything in this quest at all?! Gene-seed are unlocks, after we buy one, it stays and can be used without paying again, because they unlocks. We have only four more Legions to unlock, we can easily buy them all next turn and not have to spend resources on any Gene-seed again. It makes more sense and would allow greater experimentation with potential, future Chapters.
