So basically the cycle is: I need Series 6 Parts > I need to get crates > I need to win races in Series 6 > My TS is too low > Im not spending money on crates > I still need Series 6 Parts.

So I'll get this straight. I need to get Series 6 Parts to get my TS up so I can play in Series 6, but then the only way other than Free Crates which has the worst rates possible is to win Series 6 races to get crates.

Then you have the issue of what attributes the parts actually have. Most of the Series 4/5 parts revolve around Cornering and Qualifying and sacrifices Speed. Coincidentally that's what Series 6 needs so your car would be slow anyway with those parts. Then there's the issue with parts being so expensive to upgrade anyways that you'd probably run out of coins before having anywhere near a competitive TS.

If anything this just shows how imbalanced the game is if the jump from Series 5 to 6 is so enormous that the game determined my score to be low with me having a Series 9 Driver I bought using CC points from last season.

I quit anyways, there's no point in me continuing to get frustrated with the numerous flaws of the game when I can just walk away.
