Ok so THIS. I will say Teft has been one of my favorite cosmere characters since I met him so that does color my view but also Teft's entire character, as Harbour said, felt so reduced to a plot device in RoW.
Second unpopular opinion it seems from this thread but I actually really liked Navani bonding the Sibling? "Life before death, you bastard!" was one of the highlights of this book second only to "We chose!" Which I guess might be another unpopular opinion as I really enjoyed the time spent in Lasting Integrity. Idk the worldbuilding alone was interesting to me and while this wasn't my favorite Shallan book I did enjoy it.
But going back to Teft, Navani, and all of that... Teft's death just felt, in my opinion... Unnecessary? Like? I saw it coming with how much he felt like just a part of Kaladin's development. Where before, he did seem primarily there to push Kal forward he at least still was going through his own arc... I get that it's been a year and everything but every time we got time with Teft it felt so forced. Like "yay! my character arc is over I'm all better now :)" And specifically how he died made have to physically put the book down for a few weeks. I understand the need to establish consequences and the real dangers and whatnot, but I personally felt like we already got that through Raboniel and her daughter. I felt like we already grasped how devastating this weapon will be, so using it on Teft just seemed unnecessary other than to get rid of a character we were supposed to be done with... Honestly I think I would have preferred pushed to the background treatment...
