That would require folks to remember the Home Clans still exist and were planning an invasion of the Hansa well before the Scorps did anything. The Home Clans should absolutely be the Scorps' #1 worry, not that you can tell by the post-WoR writing, and the moratorium on their usage is the only reason the Scorpion Empire even exists in its present form. It's easy to be the perfect Clan/non-Clan fusion state when you're kept in a narrative bubble and have no legitimate threats to your bland awesomeness.
Nobody forgot that Home Clans still exist, neither Scorpions nor writers, which were getting mentioned as recently as RecGuides and latest TRO entries where it was clearly stated that Home Clans are, were and always will be Scorpions' No. 1 concern
What people do seem to forget is that they have always been one of more coherent and competent Clans albeit insular one starting from their very first description decades ago and that it was quite surprising that they even had so many problems with locals early on to begin with.
But most people just read ''drugs!!!'' and suddenly it has become core defining trait for fans while everything else gets ignored
Mineral extraction, industry, aquaculture, efficient society, freebirth input, competent touman, large garrison units composed of freebirths, effective and extensive intel gathering, etc... all forgotten. But hey, everyone knows about drugs!
In WoR Supplemental it was stated that Bastions who are absolutely dominant political current have been sending the very tiny fringe Aggressors into the region as way of sidelining the problematic personnel while they deal with matters of actual concern and that aforementioned problematic personnel only succeeded in fully, completely and humiliatingly failing at everything they intended to do other than throwing some Twitter shade at Umayyads which Seekers later cleared out with DNA testing
How long would Bastions (Star Adder Bastions of all people) tolerate these abject and costly failures before they pulled the plug and told them to get back in line?
Another thing people forget is that Scorpions were sentenced to abjuration not annihilation which involves packing their stuff and leaving which is exactly what they did. Homies will not be bending over backwards to charge into Imperio especially after Scorpions kicked out their dudes and figured out how to run the place at the turn of the century
Next often forgotten thing is that Home Clans now have proportionally huge territory to deal with themselves after Wars of Reaving, loads of planets and infrastructure that need fixing and that they also have more pressing issues to solve which would take precedence over pointless adventures in Deep Periphery and that not even worst Clan dogma would make Scorpions big enough issue especially when compared to much more ''tainted'' Clans which are now sitting right in the middle of the ''taint'' source
Cloud Cobras were unable to administer even the Tanite worlds, Scorpions solved this type of problem by making compromises with the locals which Homies would never under any circumstances agree to. This is also why Home Clan would stay out once Scorpions stabilized their nation, it had become impossible to neutralize Scorpions without going full mass genocide, again something which was stated in WoR Supplemental that dominant Bastions would want to avoid
Even with unanimous will to do it there was only <20 year window for classic quick Clan style invasion of Imperio and it closed about 3100, Clan was already fusing with locals, they were now looking at decades of guerilla campaign even if they win, the juice was no longer worth the squeeze and risks of disastrous failure grew exponentially for Homies
About Scorpons being ''perfect Clan/non-Clan fusion state' have we been reading the same material?
As much as I love Scorpion Empire they are by any measure extremely hardcore totalitarian military dictatorship which would put any real life thing and 50% of in-universe ones to shame, only difference being better amenities and wider selection of consumer goods and cable TV
Perfect Clan/non-Clan fusion state is still RasDom.
The best Clan administrators are still Hell's Horses but for some reason fandom is insistent on refusing to give them any credit for anything they ever accomplished be it civilian or military. Win invasion of every planet except one? Failure!!! Smoothly run an occupation zone, give locals leeway and keep them happy? Failure!!! Why? I have no clue....
Scorpions are still doing the very same thing they have been doing since forever and which they are very good at: sort out problems, bunker down, plan ahead and keep to yourself.
Home Clans also have their own things to do and fighting an identity-shredding costly and potentially disastrous genocidal holy war with a a Clan (of now billions of people) which isn't even slated for annihilation is not one of them. If it were writers would have left Coyotes or Cobras in charge instead of Adders.
