So drs is a easy way to overtake in this game and in real F1, in the last update devs removed completely dirty air because it was too strong and overtake was almost impossible without drs or kers, right now we are waiting for next balancement update and a revamped dirty air..
So the state of overtake right now is that it's easy to overtake slower car without drs or kers but it's very difficult to broke drs train cause drs is way too strong without dirty air and there is kers of course. In result we have all the players that stay in drs train all the race and use kers in the last lap... it's so boring and it doesn't matter who has the most developed car or the best push levels skill
In the meantime i think we could have more enjoing race without kers, drs or both, so my suggestion is to remove one of them or even both temporarely.
Plus i suggest to add a way to have disabled kers/drs for future league options.
