@Milos thanks for running this great game. I think you nailed the tyre deg almost every race, so it was a challenge to get the advantage on other teams' strategies. I remember gambling a few times and it working out some. What was most difficult for me was to guess the crossover points on wet-dry races. Especially when we had to do it many laps in advance.
It was very hard to be good the whole season, especially with the threat of DNFs on the cheaper engines. I would like to see better reliability from the start. Stroll with 13 DNFs is insane. Norris still won the championship with 8 DNFs. The worst driver in F1 this season was Sainz with 6 DNFs.
Fewer races...I'm not sure. I think this played so well because there were many races and the top teams changed multiple times. If you want us to build driver skills, then we need more rewards after a race. I rarely was able to make more than one upgrade just to the car. So, adding in driver upgrades would be that much more expensive. I'm not against doing it...just make it more accessible.
