I'm going to have to agree with luckycat. I will also say that I don't think drawing is important but understanding it is. Some people just can't work a pencil and paper to make their vision. I can't draw a dog to save my life but I could model a dog with better detail and realism. Being able to draw will also be helpful... all depends on where you're going. There doesn't seem to be much of a right or wrong answer, just personal opinions basically.
