I'm not losing sleep over this. This is the first place I can recall even seeing it mentioned. I think 6:5 blackjack (caveat: I'm not a player) is mostly to shear the casual, play-once-a-year tourist, and a reaction to the popularity of card counting, which done properly, works. I see it as an extension of worsening BJ rules. In craps, I think there is a much lower proportion of "casual players" around the table, and dice control doesn't...um, is subject to debate.
