From that 2+2 thread:
PLO Rake
While players use bb/100 to measure impact of rake on their winnings, bb/100 is not the correct way to compare rake between games. I've discussed this previously at length, so I will not belabor the point.
Our Supernovas do at least as well after rewards at PLO as they do at other games. Plenty of players are winning, and Supernova+ VIPs on average are doing just fine However, due to rake adding up to more bb/100, rewards are a bigger component of winning PLO players' earnings in bb/100. This means that players with low VIP statuses are having a harder time in PLO because VIP status has a bigger impact on results.
We'd like to do something to help players with lower VIP statuses have a better shot at winning in PLO games. We aren't confident that a simple rake reduction would have the desired mid-term or long-term result. We have a different solution in mind, but it would be a bigger change for players. We want to invite several PLO representatives for a shorter PLO focused session of meetings to discuss further. If these additional PLO players agree, we can work together to come up with the specifics of how to move forward. We hope to have the PLO players join us in late June for this discussion.
At least the admit that the rake is a killer for low limit, low status players. That's one big problem for the future of PLO, as it might reduce the number of recreational players.
