I think It's a matter of time we hear from Milestone and their new WRC project.
Till that happens, thought to start some constructive discussion posting
thoughts and Ideas of what to expect In the next WRC game.

I'll make a start:

-unique stages, no reusing the same parts of a stage.
-More narrow roads, tighter hairpins.
-Retire from a stage, not from the whole rally.
-More detailed enviroment.
-Dynamic weather.
-Dynamic time of day.
-More realistic sounds.
-More detailed pacenotes.
