The trolling part is where you come to the conclusion that the sim instructors are the reason for the unsats, and their lack of competence. I've yet to have a sim instructor who I felt was incompetent and was leading me to an unsat. And as far as the new instructors being hired, I have no doubt they will be just as capable. These new sim instructors you're referring to have yet to be qualified therefore you have no grounds for your assumptions.
