It was really good but not on the same level as Sandersons other works in Cosmere. 
 Still really interesting. 
 Since I read Way of Kings and Words of Radiance before Warbreaker it was easier for me to notice some connections. Love the fact that all of it is connected in some way and I like that it's not required to read one of Sandersons works in Cosmere to enjoy other, but it is a bonus to notice some things. 
 Will love to see how and if it all connects more :)
