You seem to be torn between your desire for differentiation and the lack of will power to take a longer break from those poor YWCs.
I'm afraid that the problem lies in the explorer/merchant - YWC and VLT are the only high XP adventures you can get easily and at low cost. So if BB forbids you to play YWC too often, can you promise you won't cry "let me play YWC 5 times daily"?
