I think thats why they did that.To up the sales of that wave. Cause they were saying there was no star power, and then they included the marvel now Thor. I feel they have been trying to use the BAFs as selling point. Every BAF so far could of been just in the wave (maybe R.R. not so much, unless he was packed with someone else of equal size.)
The 50/50s are good idea in theory, except I never see them in stores. I think Ive bought all of the ones I have from conventions or the comic shop
