Play w/o rakeback

[Jazzy3113]

As you all know if you opened an account at full tilt at the start, you most likely didnt sign up for rakeback. My question is do people still play there w/o rakeback? I mean if im not gonna get rakeback I might as well play at pokerstars right?
Is it a huge disadvantage? I have been emailing support constantly but they wont frekain budge. How can I get rakeback?
