I agree that may be a problem, if going into detail the discussion will be endless. But I think most people would agree with some generic proposals
Equal income distribution should be first point for example, I think most people will agree with this
Probably standardizing some aero parts would be appreciatted too. Everybody agree about the nosense of current low flying planes. This used to be about cars, so aero shouldn´t be so decisive
Lack of testing is another point usually critiziced
Crappy tires are another one, they allow different strategies, but they also produce so many marbles overtaking is very difficult, so they´re a nosense
Engines are too restricted too, I like the idea of free engines with total fuel limit. Each team will decide how to make the most of that fuel
Make your own, this is a forum, we shouldn´t be afraid about discussing. Let see if we can come to an agreement
