Fair point, I just think that both Traviss and TCWs retcons were pointless and annoying. I suppose at least other creators were brushing aside Traviss' when they could, they didn't seem to care for her much either.
The impression that I got (and to be fair, maybe this is an incorrect one), was that the warrior Mandalorians were all wiped out, until Spar rounded up a new batch from Mandalore and turned them into a new generation of Mando warriors.
It just doesn't make sense to me how Spar could round up a group of warrior Mandalorians that follow the Supercommando Codex when the True Mandalorians were exterminated down to the last man, as per the Open Seasons comic. At least TCW made sense in that the warrior Mandalorians were Death Watch remnants led by a younger relative of Tor Vizsla, Pre Vizsla. Karen Traviss' understanding of how you drum up armies seem to be entirely drawn from RTS games where you push a button and soldiers pop out of a barracks.
In reality, raising a full-grown man, let alone a soldier, is an endeavor that takes decades, especially when it comes to Mandalorians whose military training starts at childhood. For every one of them you lose, they're not that easy to replace. Which is why many warrior societies eventually fell in battle against large states with good logistical and population bases, especially since the latter can easily replace losses better than the former. We see this during the last war the Mandalorians fought against the Empire in the SWEU canon, where dudes in plastic armor overwhelm and decimate the beskar-plated Mandos because they've got numbers, logistics, and superior firepower on their side.





I really hate to run interference for Karen Traviss, but her main problems were an autistic hatred for the Jedi and a fixation on being taken in by a burly soldier man and turned into a rustic trad farmwife. You can also see the latter problem in how she depicts Spartans. She did make similar mistakes to the Acolyte, and worse ones at times, but her problems stem from a soldier fetish bordering on mental illness instead of having an inverted morality from prepping foundling actresses for Harvey Weinstein.
I don't mind the love for Mandos that Traviss had, I even appreciate that she created the Mandalorian language, but it was her autistic hatred for the Jedi that even I, as a Sith/Empire fan, couldn't take. The Jedi had many flaws, but in their service to a corrupt and decadent Republic, they sought to improve themselves and do what was noble and right, hoping that their service to democracy prolongs freedom and a good quality of life for the citizens.
The Jedi Order's flaw was not ensuring that good quality of life themselves, leaving it up instead to senatorial bureaucrats and corporate heads, most of whom had no real interest to improve the lives of their subjects, which in turn wasted the victories of the Jedi. But the intent to do good was at least there, unlike the Supercommando Codex Mandalorians who saw everything as a paycheck, their leader would happily kill innocent people for money, like how Jango Fett tried to assassinate Padme in AOTC.
Which is why it's fucking hilarious whenever Traviss insisted that the Supercommando Codex Mandalorians were more honorable than the Jedi, when the Jedi would literally swear vows of chastity and poverty, giving their lives to uphold the state and protect the innocent, whereas the Supercommando Codex Mandalorians would literally kill an innocent girl just because someone signed their paychecks.
People running star wars now have said continuity/canon no longer exist as they super racist and queerphobic, so whatever needs to be changed to ensure maximum niggers, faggots and trannies in star wars will be changed.
So I think that's been extrapolated by people with a vested interest in profiting from the Abused Wife Collective into "no no Disney totally has abandoned the sequels, lucas film civil war, KKK on suicide watch in her basement office. 28 stormtroopers from the 501st pulling up in black AT-ATs. Shuttles are landing. Skywalker ranch is under lockdown, under siege..."
I see that as an opportunity, my friend. Disney's SW writers say there's no longer an official canon, so to me, that makes the SWEU just as canon and valid as the Disney SW universe, and any fan can decide for themselves what is and isn't canon, or even write their own canon that satisfies themselves.
In saying that canon no longer matters, Disney's SW writers unwittingly freed the fans from any obligation to them. Now any fan can write their own canon that takes in whatever they like from both the Disney SW universe and the old SWEU, or write their own canon with their own fanfiction, and it would be just as valid as anything Disney shits out.
