I think there comes a time when you need to leave freerolls because they form bad habits. The most obvious bad habit is over betting the pot. Example,
you are dealt 
:. First mistake you bet big because you know if you bet 3xBB, 3 or 4 turkeys are going to call
2. the flop comes 

. Now, you go ALL IN!!......because you are worried of the suck out. Chances are someone is going to call so you think, what the hell all in
Both of these are bad habits that can lead you to leaving a stack of money on thetable. Bad habits can be hard to break

Sometimes it becomes necessary to break bad habits and I believe that the freerolls is a good place to practice breaking those bad habits.
The play money games are great for improving your skills as well. I see better play in the 10 and 100K play money tournaments than I do in the $10.00 real money online games.
Remember there are very few online games where the entry fee is as high as the lowest entry fee in a casino or card room. You can't get into one in a casino for less than $50.00, but online that is considered high stakes poker.
Im not saying freerolls are a bad thing. Just be mindful when you transition that you can get into over betting habits. In addition, they are horrible for trying to learn bluffing strategies because they call you down "just to see"
