Recently I have moved to playing cash games on the GG Network as the games feel much softer than most other places. I play $200nl and the rake is 5% with a $6 cap. They do have a rakeback program which claims to give 50% at the highest level but I am averaging around 30% over the last few months. Another unfortunate aspect of the rake is that they will rake pots that don't see a flop if there is a 3-bet. So, with all of this in mind, how should I be adjusting my 3-bet ranges and sizing? Another additional note, there are no HUDs and there is no way to compile hands for database review so the amount of time you can get away with exploitative adjustments is much longer imo.

Edit: Just wanted to add that this increases are required FE to break even by about 3% (using a 4x sizing) based on my math
