I know what you mean, Dude, but the GT500 event is the best there is, for now. If you go in with the right attitude (you're alright and everyone else is from the psycho wards), then you will do OK. The ghosting allows you to survive and I find that most drives can't keep up unless they cut corners. If nothing else, you learn how to drive defensively.
Two nights ago, I ended up in a lobby with one remaining driver from Japan. No drivers were added for an hour, so we traded wins until I had to leave. I tried saying thank you, but he ignored me. Today, I received my first thank you from another driver.
We can't time entry like before, but you can hunt around for friends once you know where they are. Once you are in the same lobby, you stay there.
With a 200% payout and a full room, it should be just less than 30k for a win. Could be worse.
