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.
