Playing optimally and table selecting are two different things.
Besides, even with the new changes you can still choose to switch tables if you are sat at one lets say that is full of nits or all tough regs.
The changes are frustrating though because I know last time i looked at the cash tables there after the changes there were less tables running than ever, I think if people stick around to grind cash on there I wouldn't be surprised if the changes drive even more people to their rush tables...... its what I have chosen to play when I do want to play a little cash there.
