More customization in the leagues

Currently, the customizations of the leagues are almost insignificant. A wider range of customizations would be very interesting to make your league unique. Options such as having or not having a fuel supply, number of compounds required per race, whether or not KERS and DRS have an inverted grid, a faster lap worth points and others. This would make the game much more interesting.

I noticed that many leagues have rules for 2 different tire compounds. This could be an option in the league configuration itself. It would help a lot.

I agree with you, in addition to the positive points already mentioned, players would stay more in their current leagues and would not change so much from one to other, each league would be unique according to its customization.

I agree for an extra point to fastest lap

I would also add a maximum number of wheels per season, as an option.

Just generally any more customisation would be accepted.
