> Angular doesn't provide structure for controllers, they are just javascript functions. If you want to add structure it is up to the individual developer to decide how to do it.

This is a pretty big one to me. Angular provides tons of structure all over the place, with only one real exception: controllers. Some of my controllers stick out like sore thumbs in my code. I like how Classy gives them some structure not unlike the structure that directives already have.
