You mean the ads? The earlier version of that was just an A/B test. Only a limited set of players were in the test group that got daily sponsor deals. For the rest of us ads didn't exist in-game until today. (I am assuming it is now everyone and not just a larger test group). Guess they changed the rewards for official rollout.

The rewards they changed it to is total crap compared to what we where getting. They should have rolled it out with same rewards. 

Apparently it is still in testing. They increased the size of the testing group and I guess changed the rewards, but it hasn't been rolled out. So depending on how the new test performs, they might change the rewards again when it goes game-wide.
