My Black 2 avenue is around level 50, I stopped grinding it months ago when I maxed everything I wanted. I have 3 different types of dojos (they train different EVs), 3 Cafes, 1 Mart and a Nursery. My White 2 focuses on berries, different marts than my B2 for vitamin coverage, and a salon. Its about level 20. I basically made them into one-stop training centers lol.
