Premium and Explorer (+50% return)

Would it be a good addition to have a second set of resources return and actual explorer skills (Sturdy Shovel) should count for event resources for explorers like premium affect adventure loots.

It would make a good incentive for premium and would help on event like the soccer event where the soccer ball return is low..

well the new adventurous explorer is supposed to be 50% more and that's not even working. I think BB has their hands full fixing all the broken features before adding new features.
