Untill you unlock 3-2, leveling is slow. Untill you unlock 4-3, DD/CL/CVL leveling is slow.

The wo is right, check out that blog, it's basically the best spots for grinding. Someone should poke him to add CVL to 4-3 grinding, as long as you have the helicopters from Akitsumaru-kai, you can grind CVL levels there using submarines.
