WEC really is five classes.
Under ideal circumstances, you would have two classes, one Proto, one GT, with Pro and Pro/Am so that everybody can win a trophy. I appreciate that it isn't feasible to do this.
There are two things that are truth in the history of North American Sportscar Racing.
1. Factory(Manufacturer) backed PRO racing, with factory brands has always been more popular than eras without. Can Am, IMSA GTP, IMSA GT, early Trans Am, ALMS vs Can Am II, WSC/PSCR, Grand Am.
2. Factory Prototypes have been more popular than Factory GT.
----------------------
Manufacturers are currently only interested in GT racing in North America. Unfortunately, it is that simple.
I wrote this in 2010 on the topic, very similar to what Horrocks wrote.
