I mean eventually we're gonna run out of Ford Tauruses and E150's to crush, right?
Honestly the lack of cars isn't a deal breaker by any means. It was disappointing at first, mainly because we are so used to seeing cars be such an integral part of the courses. Honestly I don't mind the lack of cars, just the lack of originality in each course design. I'm not saying that every course has to be vastly different and unique from the last, but a little change in the designs doesn't hurt, even if its just shifting a few ramps around. The jumps are a little overly steep too. Still, not a deal breaker.
The only things I actually have problems with are the backflips and the World Finals track.
Backflips were awesome back when they were newer, but I feel like the novelty has worn off for me. I think they've just over-saturated it and there isn't really any excitement anymore for me. It's too fixed and predictable.
The current World Finals freestyle track is really just two giant islands of dirt made of all these mashed together ramps with no real breathing room or strategy available. It's like if the double box jump from WF11 was an entire course. The World Finals being a 2 day event is a drag too, but I know why they do it.
As far as your comparison goes, I cant imagine the World Finals 2 track being used today for any promotion with a budget, because the trucks would eat it up in seconds. That's literally why they started making bigger, stronger jumps 10 years ago.
