- Harsher in Hindsight: Steris's 20-page marriage contract is funny, but it's sad on the second read. Steris allowing for mistresses and restricting the time she and Wax can get to know each other isn't because she doesn't like him, it's because she's afraid that he won't like her.
- Ship-to-Ship Combat: Wax/Marasi vs Wax/Steris. Some people like Wax/Marasi for being more developed throughout The Alloy of Law and because they have good chemistry. However, others prefer Wax/Steris for being atypical for a Sanderson book (being an arranged marriage rather than another love story) and providing an interesting dynamic, and would prefer that Marasi find someone else.
- Surprisingly Improved Sequel: Compared to the Mistborn trilogy, the writing style is crisper, the pacing better, the characters more developed, the dialogue funnier.
- Unfortunate Implications: Harmony created fossil fuel directly. Sanderson admits he doesn't like the parallel to Young Earth Creationism, but Scadrial is simply too young a world for fossil fuels to develop naturally, and the people need their oil from somewhere. Though note that most of what they use is bio-diesel.
YMMV / Wax and Wayne
