I hear what you 're saying and I get it, but I feel you can't judge the content you'll get off a talent based on what you get on debut. The talents will find out what boundaries they can push on, become more comfortable with their role and position in the company and so forth. Jelly now and Jelly on debut, and Ember now and Ember on debut are completely different people, for two of the most recent examples.
You're also missing out by skipping Muu. If there's one unhinged, boundary-pushing talent in the new batch it's her.
