Once RaceRoom adds rally content and features, this will be a stage to think about. However, this seems a bit unlikely at the moment. Sure, I drove Nordschleife backwards in practice once or twice and I genuinely think it is at least as good as forwards.
Why, in general a rallye stage is the same as a hillclimb stage? So we already have Hillclimb stages in the game and also the tourist layout is also the the same as a hillclimb and/or rallye stage.
