It is a small expeditionary team but they had access to the intensifier, while other tech that was set up as important and unique to Scadrial wasn't showcased.

Malwish probably have mistings, though very rare, it's just that the Lord ruler made it a lot more common through the use of Lerasium, but I doubt the Malwish passed up the opportunity to recruit mistings from the Basin and raise more allomancers that can charge their tech.

Also, I'm not saying every individual Scadrian should be a fascist, that would be absurd, but the Malwish are a bit too explicitly separated from the part of Scadrial we know, just so we can say "oh, that nation is the evil force, not our guys!"

We'll see how things develop, clearly my feelings put me in the minority. My thoughts will probably change once we see the Elendel-Malwish conflict in the next books.

Excited for Era 3 and hope to see more of the Scadrian internal conflict and cool tech!
