When Will EA Improve Multiplayer?

Well offically the game is considered "Simcade" rather than Arcade and generally speaking most of the complaints I see are people saying the game isn't realistic enough. The reason there's so many crashes in online matchmaking is because people don't take it seriously. Replacing the proximity arrows with a radar isn't going to change that.

Typically, people who are looking for a serious racing experience join a league as it's much easier for a small community like that to hold it's members accountable for clean racing.

This is arcade game, saying that radar wound make it not realistic is a bit off. You can turn it off if you want like with halo or camera you play, turning TC or abs is not realistic but it is in the game.

For multiplayer would would be big improvement, a dedicated servers with proper tickrate.

Things like Driver Rank / Safety Rank would make a huge difference. Other racing titles already prove that these systems create a much better online environment.

The license system currently in the game already does this. You start out at rank C and can rank up by driving clean and rank down by driving dirty. The system then attempts to match drivers of a similar rating together.

Also, we really need a Radar system like in other racing games.

It's an interesting idea, but I feel like adding a radar might be a bit divisive as some players will say that it's not very realistic.
