I really don't see the point of changing the caster types of so many classes. Because all that ends up happening is you replace those high level spell slots they no longer get with just magical class features. So rather than having several different options to choose from at high level (IE their spell list), the class instead just gets one single magical "thing" at various levels instead. How is that considered an improvement in gameplay? What is such the problem with getting to select 7th, 8th, and 9th level spells that we keep insisting they get taken away from certain classes? I just don't get it.
