Yes, the first RD championship that saw team Redline race and a couple of other great names was a success. Granted none of those big names competed in more than a couple of races the core of the groups was still around. We had 4 groups and only towards the very last races did we see a slight downfall in attendance.
I would very much like a championship where choices are also rewarded, ie. some sort of aggregate score given the car you chose (the worse the car is ex. E46, Peugeot 406, Alfa) the better you points tally. I understand that point might be a little hard to implement but it's a thought.
Also just like in real life we could have spots for the factory teams and privateer teams. Points can be awarded overall but there are also points for each division, this can also allow racers to chose less popular cars.
