I too think that with the current race lenght pit stops are not reasonable. You need at least an hour long race for that. But if we had pit stops, I would like a GT Open-like time compansation system. With that you always see the real preformance of the cars, and have nice battles through the race. It works quite well in GT Open.
Beside that I would love to have some of the classic veterans back. Rydell, Giovanardi, Zanardi and other great guys like Porteiro, Hernandez, Terting, Turkington, Dahlgren. Not to mention the good old BMW boys, Priaulx, Farfus and the Müllers.
I hope that the possible future change to 1.6 turbo engines in TTA will sooner or later bring Volvo back to WTCC. It was a very nice first season last year.
