This is less of a bug and more of a suggestion.
There has been a huge clamouring around the use of the Exocet in multiplayer hoppers because of how it just breaks every category it enters and literally nothing can beat it, especially lower class hoppers when it has been overwhelmingly downgraded to race against cars that it realistically shouldn’t be against.
Myself and a lot of the Forza competitive community have even made gentleman agreements about using it.
It should be removed from online play as it does nothing but break open any sort of fairness to the game and the PI system does not accurately reflect half of the cars in the game and their reflective performance.
Things like the Miata and BRZ are fine as most people can beat those with other machinery if in the right hands but the Exocet is practically agreed to be the most broken car in the entire game.
It could also force nothing but lobbies to run only that one car to even have any sort of competitive edge.
A possible suggestion is to remove the engine swap options from the car to force it to stay within more accurately competitive lobbies, if not removing the car from online play.
