You don't seem to get the point. There were times when it was enough for You to win a world title in PWRC to have S2000 car as there were only one or two yet nobody was running to WRC. IRC had up to 30 S2000 cars on start and PWRC 1 or 2. In that time it was also world title but nobody cared as IRC was a lot better place in terms of competition, recognition, marketing etc. While it's not possible for ERC to compete with WRC for obvious reasons it is definitely possible to fight with WRC2 and to attract more competitors as WRC2 in terms of marketing is pretty much non-existent in the media. As I said they don't seem to care anymore.
