That's why I do believe that rallying should have taken a step back and for a couple of years make Rally2(R5) their main category as well.
I do understand that it wouldn't be as spectacular but we would have got a lot of brands and cars to challenge for victories, and then maybe renegotiate with the manufacturer's broader regulations.
Look what happened with GT and Touring Cars. Both of them have nowadays cars that can be used anywhere and bought quite cheap and they are thriving.
