Thanks Mark, I love that you responded to this thread!
I don't know that if I got 2 rares out of 15 that I would be so miffed. (1/21 was my result).
Just a rhetorical question: Wouldn't it be better if your gold spenders spent gold and felt GOOD about the outcome rather than the feeling that they got shafted? If ever the statement "Under promise and over deliver" should be followed, I would think it would be in these cases. Virtual rewards! How easy is that to over deliver?
