I love racing the C-class introductory but why not expand no collisions to the other classes? Also, Why are there only just a few tracks cycled in the C class introductory? As a player/racer it would be a nice option to be able to choose my class, choose if I want collisions, and have an algorithms chance of all tracks.
There is a no collisions lobby in league play however the restrictions vary from week to week.
The introductioary lobby is where noobs are supposed to go fine tune their skills before jumping into collisions lobbies. Obviously that really isn’t the case.
There is some sort of random track generator for other lobbies where you can vote for next track. Leagues have a set track rotation however.
There likely isn’t enough people to justify having a no collisions lobby for every class.
To me it seems like you would like what custom public lobbies provide if they actually existed on Xbox one forza games.
