If you remove the rake race, you will still lose players in my opinion ...
I do not understand why you do not put zoom poker ... It would be a solution for players who do not know how to run your app and who are forced to go through a browser ... I have 2 friends who still do not know Not play on your new software and they do not want to play via browser ... If there was zoom poker, they would still play at home even with the browser!
I think you do not have enough players to propose other variants ... And especially not formats banzai kind, you will still deplete the number of players at other tables ...
You have to realize that regular players are at home for your innovation and your games weaker despite the fact that you do not have a rakeback system ... If now the level naturally becomes higher, you remove rake Race and other ...
Your software is very fluid but it is still quite heavy unfortunately.
Congratulations on your promotions and good luck for the rest
