I bought premium after the free 3 day package had expired. There was this decent offer of x2 quests per day but today i noticed that you don't get rewarded for performing the 1st set tasks. Only the second set of quests give you rewards. Also the 1st set can be completed simply by playing one game. I mean you don't even need to satisfy the objective of the 1st set of task. It simple shows completed and jumps to the 2nd quests. The same for X-cry quest. Only the 2nd ones reward you.
