Desolas, if you don't want to move up you don't have to, but if you're looking to improve yourself or show potential sponsors how good you are wouldn't you rather race in the faster class with the better drivers?
Let's flip this, you have the best motor, best batteries, and best car, and you're a very good driver. You race in a class with cars half as expensive as yours and okay drivers. You TQ and win the A by 2 laps.
What have you really proven?
And, what about the 3 new guys who came out to race, took one look at your stuff and said forget this I can never compete with this guy.
