My best math class was with a professor who did not use a textbook at all. He created ~5-10 problem long homework using a pdf we could easily get from his page on the school's website.

The focus universities have on homework is absurd. If you want to practice 100+ math problems, you can invent them yourself, or even find plenty on the internet. It only takes one or two problems to show that the student understands the subject matter. Any more required homework is a waste of everyone's resources.
