Every year I blow all the leaves into piles and remove them the compost pile. This year I have not removed one and chopping them all up. Mover height is around 3"-3.5" down from 4-5" and Gator blades are on my mower. I am using my entire lawn as a test plot, I have not removed any leaves and only chopping them up each mow. Requires a double cut or triple cut when very wet each time and lawn still looks good after. Today I did wet leaves and they chopped just fine. I know worms love fresh fallen leaves to eat, so by me doing this, it should make the worms very happy and build the soil.
