My suggestions to improving Underground Rivals

I couldn't agree more. I've been spending my time and improved my cars for nothing for last weeks. Always the same diagram repeats again and again. No way to beat B class for this week for a fully upgraded 370Z, last week was the same for class A and Mazda RX7.
Well, my suggestion to stick to the subject would be to give a chance to the car of the same model to shine for two days a week. Let me explain.
There are usually 3 cars per class, increasingly stronger, with 0 balance regarding the last one (paid car 100%, legit or not). First day could be "royal rumble" with all cars in competition, but 2nd day could be dedicated to the slower model, 3rd day to the 2nd car, and 4th "royal rumble" again, etc... That would be much more balanced than the total mess we actually have to face and sadly suffer. I'd just add the result of my last 3 races in the easiest division B class, all lost obviously, to help understanding the meaning of "totally unfair and unbalanced stuff you sick people at dev team".
