It does indeed appear like they have pulled a bait and switch. Here is the new prize chart:

With the new odds it becomes virtually impossible to break even unless you actually end up winning the lottery or a lambo with your tickets. If you somehow manage to make 24 claims in a day to get 120 spins you will only be expected to earn a combined 3342 RP & sats while the cost to activate the bonus is 3600 RP.
With these adjustments it also makes it much less appealing to become a premium member. With FUN token hitting new lows against BTC since it was introduced to the site and the WOF prizes constantly decreasing, the vast majority of long term investors might end up losing more BTC than they earn.
Hmm, so it seems that the chances you can win a nice amount of satoshis or rewards has dropped with a factor 10, which is quite a lot. You are right that it is not interesting to buy the bonus (extra WOF spins per extra free roll) with your RP as the maximum a normal person will be able to claim is 12-14 times.
