@orclover, I'm not sure I follow your reasoning above.
Logic dictates that with each event there are going to be people who spent credits but didn't win anything.
Yes, that's definitely true. I played the scratch card game when it first came out, mostly for the novelty. I won a couple cards that I didn't like and haven't played since because I only want 1 of the 4 special event cards that I don't have.
Every event will have a smaller % of people participating and the number of cards sitting on the server not making money will grow.
If Totem continues to make special event cards, then eventually there will be enough special event cards that I want to make me willing to gamble again to get them. The question is whether people like me who would be incentivized by more special cards would outweigh those who have become disgusted with Totem (and themselves for overspending) and would never participate in the gambling promotions again to get those cards.
Also, I'm not sure if people are generally as smart as you consider them. I know plenty of people who have lost more than they have won in Las Vegas and on lotto cards, but somehow that doesn't discourage them from continuing to gamble.
