It seems it is targeting MTT players only, which is pretty lame. There reasoning is so they can put it towards "what matters most" which is keeping there ridiculously large guaranteed prize pools, which they seem to hit anyways. So pretty much they take half of everyones rake so they can cover the overlays.
I do not play much volume at this room, so I do not receive many chests, but I can understand how people are unhappy with this.
Other rooms do not have nearly as much traffic as this room and offer much better rewards and rakeback offers. They make so much more money in rake then the other rooms too.
This is a good chance for another room to step up and offer better a good rakeback and reward structure for high volume players aswell as good promotions,
freerolls and bonuses for casual recreational players.
