Good job on the online process, glad that your skill have not rusty. So for career; keep practicing on certain track and learned your mistake from where you couldn't able to overcoming. I heard that one player managed to complete the Expert Class on the World Tour within a week.
I used to be hearing person like you, until I took the fever in my ears. ~FredCat
I don't find Expert difficulty hard either. You just need to keep practicing. Go to Single Race mode and play at any track you like on Expert. Its a bit daunting at first but after a few hours, you will realise you should be able to come in 1st if not 2nd everytime easily. The only difference between Expert and Normal is that the cars are much faster and the AI has better accuracy with their weapons. But neither should be impossible if you play smart and run good laps. Recommended car to use is BD Joe standard mod. He has good stats.
Driving a PC racer with the keyboard is about as effective as typing an e-mail with your car's steering wheel. ~ Brian Ekberg
When I first got the game I thought it was unfair even on hard, and expert was just terrible. Hit the Triple-Star Licence earlier and I beat expert races 100% of the time (Traffic Attack is still terrible though)
