This is not a light read! Here are the details:
- When you change leagues, your designs are now completely re-generated according to the state of the new league, using your current (active) Chief Designer.
- If the new league is in the first race of its first season, designs will be totally reset, as if you were just starting a new account. Because this will be the same for everyone in the league, nobody is disadvantaged.
- If the new league is in a season greater than 1, then your designs will be scaled to the progress of the season. For example, if the season is in race 10, then you get "10 races of design progress", and if it's in race 16 then you get 16 races of design progress. This is applied to both the current and next season design, matching all progress to the league.
- The exception to the above point is if you join a league in a season greater than 1 while it is between seasons. Then you get a full 17 races of design progress, as if you had been present in the league for the full previous season, while your next season designs are completely reset and must be built from scratch (the same as everyone else in the league).
- Design Points are also given when changing leagues, scaled to the season progress. 1 per race in Rookie, 2 per race in Pro and 3 per race in Elite. E.g. if you join the Elite tier in race 14 of the season, you'll also get 42 Design Points to spend on your car, in addition to the base design created by your active Chief Designer.
The end result is no exploits can be made on designs by league hopping. All teams, whether joining or already in a league, get a fair outcome and should be relatively competitive. The effort put in to building a team is still respected, as the HQ and CD influence the values generated. Those who have managed these well will get better designs than those who have not.
Lastly, a note for the experienced players:
For those familiar with how "next season designs" were generated previously, this algorithm is what is used to determine the new design levels. Each increment for the number of races is what would previously have been a single race worth of progress on a next season design.
