Don't get me wrong, this is a great book. The issues I have with it are totally my own.
For me there is just to much war and politics. I really only have one MC and one secondary character I like. Everyone else I am either neutral towards or dislike. That in itself nearly put me of reading to the end. 

But, as usual with Sanderson books, I find the world he built fascinating. I love the way we are gradually introduced to it and the magic system.  It does not feel so overwhelming as with some authors who try to infodump everything early on. 

I will continue with the series.
