Village Greens: CL 1 to CL 2
Bill's Ranch: CL 2 to CL 3
Zen Gardens: CL 3 to CL 4 (Personally, I'd go at CL 4.5 before moving on. Those wolves will eat your lunch)
Bass'Ken Lake: CL 4 to CL 6 (you'll have to do repeatable to get to CL 6, but it's almost vital to be at least CL 6 before moving on from here)
Old Aqueduct: CL 6 to CL 6.5 or 7
Golds Beach: CL 7 to CL 8.5 (I added the .5 because it's easy to get swarmed in Otami Ruins)
Otami Ruins: CL 8.5 to CL 9.5
Shallow Seas: CL 9.5 to CL 10
Deadman's Shadow: CL 10 to CL 12
Not sure if this is what you're looking for, but that's how I interpreted your inquiry.
