That sounds terrible in general, but more so when you think about places like RD where races with multiple cars are often used.
If they allow mods to also be used then we are ok, just never touch the default content.
If mods are not allowed then it just turns into "ok guys, in this race we are using these 5 cars, go buy them now kthx" and that is not ideal. Or, perhaps just "anyone with this one specific car, join up" and see a lame turnout.
At least with different expansions, content is lumped together instead of each piece being separate.
Either way it is going to suck imo unless they let you be in races if you did not own all the cars(except one) by either having the models and not letting you use them or loading a black default placeholder like in forza.
And if they do not allow mods, I worry about the content. Coming from GTL where there are so many car and track mods perhaps I am just spoiled. :/
But I could of course be wrong. They might just do the Race 07 thing with expansions again and nothing will be different. but normally from what I have seen in F2P games you do not buy groups of content, you buy it individually.
That is concerning.
