Are the last 2 livery packs not included in the season pass?
They should be, it's an error on the store that should be fixed soon.
MP time trial sounds cool.
Race one sounds a bit time consuming though.
I had a multiplayer race where everyone else was a ghost and it was great being able to just drive the racing line without getting shoved all over. It is nice when you do put a clean pass on someone in normal multiplayer though so I wouldn't want to replace it, just have another option if your fed up of being rammed.
The race of champions thing would only last 4 races at most, and less for most people :-
Round 1 - 12 players, last 4 knocked out
Round 2 - 1/4 finals, 1 v 8 etc
Round 3 - Semi finals
Round 4 - Final
It's like a party mode that you would've seen in an old burnout game. I just think it'd be more rewarding to have an event that lasts more than 1 race, and a cup style event where people are knocked out probably works better online than a league (where they'll probably leave if they aren't doing well).
