“It’s probably Matt Mercer’s fault.”
But in all cases you are trying to do that by taking away from existing classes, more 'options' at the cost of existing ones. Which many times does away with what people like from those classes like about the classes. And your choice of which classes get spared and which classes are 'prescindible' is skewed towards messing up with the interesting stuff while keeping the wizard and cleric intact. Which isn't very palatable.
The same Vancian mechanics for every caster class is "the interesting stuff"?
Huh.
