Multiplayer players and rules !!

Completely agree. There needs to be a more severe penalty when the driver is clearly looking back waiting for the opportunity to ram you off the track or brake check outside of braking zones, forcing you to either pit for a new front wing or DNF while they drive away essentially penalty free.. because let's face it, warnings don't do jack. Find races that are Safety License Level A and its the same. You might find a good lobby (I would say the percentage is greater than Casual or other 'Open' lobbies) that way but its still a poor ratio of good quality racing to obnoxious drivers. 

Also, if you qualify outside of P3, I feel you spend the beginning of the race waiting for these fools to DNF (if you weren't already rear-ended by someone who doesn't believe in timely braking going into Turn 1) and by that point, P1 is long gone.

The reporting system needs actual consequences or if you are the cause of a driver to DNF because of a collision, automatic anti-grief so they cant cause further chaos and loss of License Level (either straight to D or 1 level, depending on repeat) so A class can race with quality and a little bit more peace.

Improvement and stricter oversight of players reported is needed for Multiplayer races. You try to find a league but the EA Racenet app is down a majority of the time.
