Hate sounding like a broken record but the majority of these changes won't mean anything in career mode due to stat boosts.
That being said, some of the changes are okay but there are definitely some that make me think "wtf".
Lewis pace buff is fine but it needed more, like 93. The awareness nerf I just cannot understand at all. They've just pulled it out of their backside. If it's because of Austria why did none of the other penalised drivers get awareness nerf and why was Lewis' so big considering out of 300+ races it's a very minor thing. A 1 or 2 nerf at most.
Russell nerf is fine I think but the Alonso nerf doesn't make much sense. The career boosts already make it difficult for Alonso to finish where he should be and now it'll be even more so. Just because the car hasn't developed as fast as McLaren and Merc doesn't mean Alonso has been any slower. It's just a random change for the sake of change.
Sainz is a bit overbuffed I think.. he's not that close to Charles. That being said, Leclerc does get 91 pace fairly quickly so there's that I guess. Perez nerf is good and so to is the buff to Zhou.
Hulkenberg definitely needs a bigger buff than he got here. He should easily be at 84/85 pace with more race craft as well, Magnussen didn't need a nerf I don't think, just needed a bigger buff to Hulk.
Albon and Sargeant buffs are good, nerf to De Vries is irrelevant to be honest if they're putting Ricciardo in later.
Ocon nerf makes no sense to me, he's been better than Gasly when we look at it really and yet has two pace less now? Nonsense. Piastri definitely needs a bigger buff but they've got to be careful with him due to how fast his stats grow. I think starting him at 82 pace would be fine.
I'm just dreading the incoming Mclaren buff which is going to destroy the balance of the game. They already perform well thanks to the stupid stat boosts and they improve rapidly. Norris is already fighting for podiums in my saves and I'm only at Miami... If they buff McLaren, they're going to be overpowered once again, just like last year.
