Updated rating. Expect no issue until Tier 6, at this point materials become few and far between and it's where the micro trans comes in, majority of races are full of AI teams with top upgrades so expect some low placed finishes unless you prioritise and invest in one top driver and are clever with strategy. That said, there is a good variety of tracks and weather patterns, I have to say no one race has felt the same as another, and strategy is actually applicable rather then just an illusion.
