I don't think it's a bad idea - it would be an interesting thing that doesn't actually affect game play but adds a little bit of extra mental or emotional investment in the characters. I'm not sure how that translates into money for CG - which is primarily what drives their development resources (understandably).
But I also can't say that it's something I'd rather have in place of several other frequently requested features that do affect game play.
Yes, I agree this update isn't a necessity. I also understand it doesn't drive sales but neither did the portrait update. Which updated a bunch of portraits of older characters. It was just something they did. Once CG smooths out a lot of the gameplay suggestions that others have written, I don't see the harm in adding new content that isn't a new character.
"But I also can't say that it's something I'd rather have in place of several other frequently requested features that do affect game play."
I'll respond with a snippet from one of my other responses:
"...The devs don't need to implement it in the next few months or even years. It's a suggestion. They can improve all the gameplay of the game whenever they please. If they decide to try something new, this suggestion will always be here."
It's also nice to just have a new suggestion for a change. I've seen too many people suggesting the same thing and wanted to add something new. Innovative suggestions tend to get shot down because people are too focused on what the next update should be. As if my suggestion was going to cut the front of the line and rob them of better QoL updates. That's not the case nor do I want it to be. It's here in case CG wants new ideas.
The suggestion could also be built upon too. What if the characters' biographies are unlocked when you 7* them? Might make 7* a character a bit more rewarding. There are a bunch of collectors in this game, maybe that could be a way to get more people to whale on new characters?
