They deceased the min limit to 0.002.I think it isn't necessary to set it even lower.faucet is also disabled when you got bank balance. At PD you can bank to your alt and use faucet over and over.
Actually the faucet is giving us 150 satoshi and primedice might cut it again when price of BTC will go significantly higher in the future.
I don't think that there is a good way to farm faucet with the limitations, there is a withdrawal limit, you can only claim faucet while your balance is zero etc.
And one more thing to add about it sir, you can only withdraw when you reach the limit, but how? that is why you need to play to earn and reach the limit so you can withdraw. I agree with your presumptions and maybe it would be turn out reality in the near future about the satoshis given by the faucet that will be cut.
