Reducing the effectiveness of drs
I've found in my league and others that due to the over effectiveness of drs, it's actually ruining the racing and making it a one lap shoot out with boost on the last lap.
My suggestion is drs gives a lesser advantage to allow for breaking the drs more easily which would then mean boost is used more readily throughout the race.
To be able to catch someone half a straight away because of drs is rediculious, even if it's a game not based on real life which I understand Devs don't want it to be. Having tyres and fuel reasonable but then having drs overpowering makes no sense
