Homologation "solved" the missile cars and stuff, but it still has leaderboard cars that are OP and people don't like seeing in lobbies. People doing anything they can to get a slight advantage will never change though, every system they come up with will have people trying to exploit it.
Personally, I like the disparity between speed builds and handling builds when running at "normal" somewhat balanced tracks and when they aren't taken to the extreme like many would do with their missile cars. Having areas of the track where one car is weaker than another leads to interesting racing, which is something Forza has generally lacked since the rest of its race stuff is shallow (tire wear/strategy/etc). Le Mans with missile cars in the lobby is zero fun, but someplace like Catalunya with only one big straight? Those can be interesting races.
Thoughts on Bernese Alps if that track makes it to FM?
Worst track in Forza's history, I'd happily sacrifice it for just about any other track.
Understeer central, and doesn't really have any passing zones that don't rely on the car in front screwing up and understeering out wide. That leads to a lot of morons online going for crazy dives and washing up into your door and screwing you both up. Maybe if the game had drafting that actually worked right then it could be tolerable, but particularly within the context of Forza it is an awful race track.
It is a great example of T10's fantasy circuits being graphical showcases first and race tracks second. In FM1 they had the Alpine Ring, which was an excellent track and all they had to do was give it a fancy vista and some ski lifts and other junk and we could have had a track that was both good and pretty, but no instead we get Bernese Alps and the FM1 fantasy circuits, that were easily the best fantasy tracks they have made, get abandoned... Well except Maple Valley, which is the worst of the FM1 fantasy tracks.
They did acknowledge the recent run of fantasy tracks have been generally bad for racing and said they are trying to change that, so hopefully Hakone is better. It will be interesting to see for sure, because I think the last time T10 made a fantasy track that actually felt like it was trying to be a race track was Sedona? It was actually an alright track, but I'm sure the people involved are all different now, so it will be interesting to see what we get.
