Thank you for the responses. I understand and appreciate the various points of view, but I still think that studios could increase their participation from students in showcases if they gave them a bit of a break. Anything you can do to make people want the services you have to offer will only increase the demand for those services. Increased demand will bring more profits; whereas, squeezing the blood from turnips will only bleed them dry.
Over the years, I have seen a decline in participation due to people being used as the studio cash-cows through the showcase mill.
