I can see a single massive issue with the Shinovar campaign. Szeth is insane and on his fourth ideal crusade. He despises the false Shin leaders for making him Truthless and making him kill. Ishar straight up murdered Szeth's father. While we know Ishar is not all that reliable, I think he is bending the truth. Even if Szeth's father did beg for death, I hardly think Szeth sees it that way. So Kaladin and Szeth are crusading through Shinovar with an insane Skybreaker wielding unsheathed Nightblood and seeking out a man who killed the father of the afformentioned insane Skybreaker with unsheathed Nightblood which can most definitely kill him. How do we know Szeth won't just murder Ishar and commit mass genocide? This means Ishar may never be able to reforge the Oathpact and completely mess up the protagonists to set up the second arc.
