I personally think that currently newer players to exit path are having a hard time actually learning the tracks because their upper-ranked opponents are too fast to allow them to actually finish a single race. I think that if there was to be an addition to the original exit path (which I highly expect) then I think there should be a small mode where a player can freely move about a multiplayer map alone to create their own personal techniques and strategies without having a time limit from opponents finishing, or having to worry about their records being desroyed. More experienced players could also test new tricks of their own and master them down to become even better competitors.
This is simply just a suggestion and I know this would be alot to ask but I think it would really help out the exit path community all together.
