There's far more money to be made in D1, so that's not very good reasoning on your part.
Unless you alter your strategy, I think you'll be stuck in D2 for several more seasons. Only one team promotes and there will always be at least 1 team doing whatever it takes to get out of your division. Although you previously said that you were against doing it, buying a stud or 2 to help you get out of D2 is actually a sound strategy because you'll need players like that to survive in D1 anyways.
