Red Bull are dominating now, Mercedes had a stranglehold for a decade, Red Bull had a few years before that, and Ferrari dominated for years. There's always been one team dominating and one car that's super faster than everyone else. Last year would have been a great title fight if Leclerc was a better driver and Ferrari were a better team.
I do think they need to trial some races without DRS to encourage genuine overtaking. And I've been a strong advocate of refuelling being brought back.
