I'm not seeing where they make you pay rake on the bounties from KO tourneys, but I guess it could be construed that way. They did raise the rake there, but that was to push it more in line with other tournaments at that level – which makes sense honestly. KO tournaments are going to have more backend required to run – more transactions requires more bookwork in the backrooms. So offering them for less rake than they would get standard, doesn't make sense.

The MTT end didn't really get hit too hard here from what I've read, but the Hyper guys are lit right up about these changes. I've been following the thread, and it's chaos. I'm mixed on it, because I can understand why Amaya is doing this from the business end, but no one ever wants to pay more rake.

The side note though, is this might acutally burn off a lot of the very marginal ROI guys that clog up a lot of the seats, the so called “regs”. They will no longer be able to turn profit off their micro margins, which means they won't play anymore. While this will likely reduce traffic, it will be nice to be able to play certain game selections and not be always playing the same 4 regs – a situation where I know I'll be losing long term, so I just avoid. 

There could also be a lot of other reasons, such as increased cost of operating; They will have to share profits with charities/tribes/gov'ts now that everything is becoming regulated. Amaya now has a huge debt, and isn't going to want to burden the loss of profit, so they will pass that onto the customer. It's how business works.

At the end of the day, they are really minor increases, and they won't effect the majority of the poker playing population to a very noticeable degree. The players who get it really bad, are the break even rake back grinders and the high volume guys.
