Unfair for new trainees

I think it's very unfair that the new trainees have to compete with idols who have already debuted and already have a fandom. In other survivors I've seen that there are debuted idols who also participate, but in smaller numbers and only 1 or 2 get screen time, here there are many idols who have already debuted and receive more screen time than the new trainees. They should have made The Unit 2.0 and only accepted debuting idols, that would be fairer.

The final top 9 will be made up of the debuting idols + the center.

I feel sorry for the new trainees, who don't have a chance against other participants who already have a fandom. ☹️
