Rally2 as the top category is the most viable way for WRC at the moment. There is an abundance of cars available, from a variety of makes. It will open up the field hugely and allow youngsters and local talents their time in the sun, (which has always been a WRC staple till about a decade ago). Adding local interest and the element of surprise will drive up visibility. Even allowing non factory supported cars like the Mirage R5 and the Holzer Corsa can help too. Will also allow exceptional talents with R3 cars to shine by mixing it up with the bigger cars, instead of living in anonymity as is the case now. Yeah, ok, R1 are much more spectacular,but a 6 car championship can't sustain itself for much.
