Do the old Sansha missions make sense without the new AI? Not really.
Yes, they do. The Sansha we've seen for so long were stated to be remnants of the Old Nation, automatonic fleets simply following the last set of orders given. The New Sansha fleets are freshly built fleets, full of new tech that has been in development all this time, crewed by the victims of the Initial Incursion planets, and commanded by Sansha himself. Of course they behave differently.
The 'old' Nation remnant is still out there doing it's thing. Sansha just hasn't switched it off. Then again, maybe he can't?
"Attacking from a location which remains yet a mystery to CONCORD" makes more sense to me than "attacking from that area of space, let's not go there".
This makes no sense. Having an imagined, off the map origin is better than one that is explained? I vehemently disagree. In this case, Graelyn commands a force of 70 titans in an unexplored system, surely.
They are maniacal terrorists, looking to destroy. How does that not work in an Incursions setting?
The basis of the massive amount of personnel Sansha deploys is explained, both in the activities of the Remnant forces working all this time to harvest what they can, to the mass abductions in Empire space, and even a constant trickle of consensual followers trickling in from the Empires, people who believe in Kuvakei's dream. You have a massive slave force augmented by implantation, and devout followers.
Small extremist cults like the EoM remain small due to the outlandishness of their goals. It's hard to fathom a more extremist cause than the one they follow (Kill all life! Period! Arrgh!). There would be no massive influx of men or materiel. Hardly anyone would join them on purpose, and there is nothing in their background that points to an ability to force a population into serving them. As such, any attempt to shoehorn any of the above into their story would be completely pulled out of someone's ass with no supporting data. That's the sort of thing that no believable story should allow.
There is no basis for anything EoM related in an incursion setting. An argument that 'well, nothing says we can't' is not just a slippery slope, but a sheer cliff into a rocky ravine of doom.
After having Sansha for the live events, I found the choice of having them do Incursions to be a bit unimaginative.
Perhaps you wanted a group
less likely to invade the cluster to go ahead and do so. In my view, a group that seems likely to do something should be the ones to....do it. Things making sense should be occasionally encouraged.
And it makes the old missions and the fact they hold territory without a massive CONCORD-led invasion to be illogical to me.
Here you have a point.
