My opinion will be more polemical on this, but I think the most accurate.
The DRS should be completely eliminated, and the dirty air increases its effect a bit.
The wheel on wheels totally changes the way you play. Before, when changing drivers were directly looking to go faster and try to move away from the rival, which made different track and strategic duels form but right now all the riders who are going to fight forwards prefer to go in PL1 than accelerating, why nobody wants to be the leader and exposed to being overtaken by 5-6 cars with DRS, which makes very boring duels as they do not rely on gas management, pushes, tire strategy, but whoever keeps the DRS longer also has a counter effect on reloading kers, since many direct don't use it when leaders want them ahead so take drs.
I feel that the best thing would be its total elimination, and change it to a 2% kers reload per round, plus slightly increase the effect, either from dirty air, or clean air, in that way, someone who takes the lead what will try is get away, whether using Kers for that, or PL5, and someone who stays behind the leader, will more times attempt overtaking with Kers as he needs to avoid getting into dirty air.
This measure would also help people by means of strategy decide to stop earlier, and you can use the Kers so take advantage of your new tyres, or vice versa, decide to stretch a turn, use their Kers, push up, and get out in front, but as it is played at present, no one wants to fight, everyone wants to go slow and stay with DRS, and takes away any dynamic into battles why who starts for P7 knows how to keep train will escalate while leaving tossed to P1, whereas whoever starts P1 will be less likely to fight the victory pole, that's why not worth much either, since you easily lose being the victim of DRS.
Better than that, put an opción in gold league to activa te or deactivate drs
