Nitemare and I were discussing doing a couple of events for SummerSlam, but never quite got round to it. We've also worked out a way where it'll be impossible for gamblers to be guaranteed a profit (hopefully), as that was the flaw in previous events, hence your "richness". There should be some events for the next PPV.
The very first event I did was a joke. The second event, which can be viewed here, already did what we discussed. I was just being generous because it was the first actual vBookie. Then SmackDown!'s Cage Match was also a way for members to get some points.
There's no flaw and there never was. I was just giving members who use the feature a chance to profit.
