Before I read Way of Kings I read that Shallan would have the flashbacks this book. During my read, I started disliking Shallan and definitely wanted Dalinar or someone else to have the flashbacks. But once she admitted killing her father and when I found out she had a Shardblade she is the one I want to read about the most. She went from being my least favorite character to one of my favorites really quick. I want to know why she killed her father (I assume he raped her) and I want to know the situation of the Shardblade she has.
I also thought all of Kaladin's flashbacks, besides the battle when he won the Shardblade, were really boring.
