THERE IS NEED TO SHOUT. Oh, but the problem with that is nobody would ever use them after the first month, and putting it in the game would waste lots of time. However, they could remodel some of the games dev system etc so rookie is GP3, pro GP2 and elite F1, with different car looks and dev rates ETC
When you first started the game up until you bought KERS & DRS at level 5 you where a lower formula team.
Lots of the suppliers are already there all that would need adding is more options to the league setup page.
I don't see how expanding the game to allow for the use of other formulas would be a waste of time.
Cars doesn't have to look different to be different, development rates are based on the league schedule.
