I think rake is OK so long as its reasonable. I was playing 500 point buy-in on FRC heads up, after about 15 min we were both losing like 50 points because of rake. IMO that means that the rake is way way too high. If you kept it at a 3 pt max and no rake unless pot is over X amount then that would be ok. But the rake on FRC, imo, is fucking insane.
