Wow, I cannot keep up with everyone else in this thread!
I'll admit that Shalladin was the first ship I ever felt actually invested in. Usually, I'm more than happy to let the narrative take the characters where it will. The fact that I felt invested from the moment Kaladin and Shallan meet in WOR tells me that there was something real there.
That said, I went into OB ready to be convinced that Shadolin was the better route, if that was where BS wanted to take his story... but, well, obviously I'm still unconvinced. I'm just so glad to know I'm not alone.
And, @PhineasGage, I'm looking forward to your fanfic.
