I would be really keen on an "RDRC Academy" Category. Either one-make Fiesta R2 like in real life's WRC Academy (now Junior WRC), or the entire R2 category. I felt like the N4 cars were the beginner options for the RDRC, but I was still crashing a lot
, and feel like R2 would be a better option.
That said, I don't think it should be mandatory, some people could definitely find it too slow. But for beginners I think it could be helpful.
I also think grading should just go away and be replaced with the option of changing class during the season. This would lessen the work load on the directors, and I can't really think of any negatives - if someone picks a car too fast for themselves then they can just move down.
I find the new classes kind of confusing, but I'd think something like this:
Overall (includes all Rx, Nx, and S2000 cars as well as A8W_11/12/13)
WRC-2 (includes R5, R4, S2000 and N4) (and RRC?)
-WRC-2 Production (includes R4 and N4)
WRC-3 (Includes R1, R2 and R3) (And other 2WD cars?)
-RDRC Academy (Includes R2)
