1-2 NL Rake

[ROACHBABY6978]

Just started playing live 1/2 NL recently and had a few questions.

1) What is the usual rake for 1/2 NL? Where I play you must cough up $6 each time dealers switch (every half hour) for a total of $12 an hour. Is this normal?

2) I know the answer to this question is going to depend on a lot of factors, but in the most general of senses is this 1/2 game that cost you $12 an hour to play going to be very profitable? The buy-in is between 100-300, and like most live 1/2 NL games 80% of the players were pretty bad.

So how beatable is a game like this where you have to make $12/hr just to break even?
What kinda win rate could an average player expect? a good player?
