after dominating tier 1 to 5 you reach tier 6... thats where paying players dominate, with free players like me struggling to pay driver and engineer contracts and barely enough parts to upgrade and only few hundred K's of cash to spend. races goes bad from race 1, with a nearly impossible chance of winning the registration fee back... now I only race a few tmes a day, waiting for sponsor cash to register a race... definately not enjoyable anymore.
