And there we are again
We dont need to convince anyone of the
wrongs of their opinion - simply because there is no wrong.
Just dont do it if you dont like it, other will continue if they think its fun or advantageous, and neither side will have to confront the other for anything that they dont like to see, because not taking part is not only possible in single player activities but actually the only way.
You dont lose your fun of driving all tracks when someone else spends his time in a moneyloop on a specific other track.
