I feel like I'd rather just have all the new 30 cards be class cards. I love Shaman but there is seriously only one way to play him. While the neutral cards will shake up the archetypes for the classes a little bit, more class cards would go way longer in terms of variety I think. Though, maybe it's not worth just adding 3 per class, I don't know.
Picture this; you're both playing Wipeout for Kinect together. You accidentally fall on top of each other onto the floor due to the strenuous activity and that causes you both to look into each other eyes, with a smile. Then, you make your move! And, then the Kinect, too, makes it's own move. By sending the data of you two having sex to the NSA. Enjoy your date.
I had the exact same reaction when I first played it and it took me my second run through for it to click. Honestly, it's kind of amazing how much of a missed opportunity the story is. And also the powers, too. Sure looks pretty, though!
