I like the idea of the Adolin Shallan ship for the development opportunities it presents in the next books. Adolin has always been the Golden Child, excellent at dueling, and quickly growing to fill his fathers shoes when he finally steps down. Shallan's coming out as KR, along with Dolinar and Renarin, will force him to adapt to being the least "powerful" in the group. His relationship with Shallan WILL be tested, but I think it will be a good experience for his character. Whether it not it turns out well...that's a different matter. But for the time being I'm hoping this ship keeps sailing.
