Au contraire, I think this might be more harmful than good. Characters who get added to this pool are the ones who have been powercrept so bad that they’re never going to see the light of day anymore, even at E6S5. By comparison, characters in the shop on the other hand, are still decently meta relevant, like RM and Luocha.

If you’ve been playing the game for a long time, you’ve likely got multiple eidolons for most of your standard units. Which means, you’re closer to getting those golden spirits and accessing characters in the new shop. Now, what happens if you replace some of those standard characters with blade, Fu, or Seele, who you’ve likely only got at E0, or maybe E1 tops? You’re going to take much longer till you start getting the golden spirit tokens, and by extension, characters that are relatively more valuable.

That’s my consultancy theory anyway. If you want these 3 charcters, wrll, good for you. But I certainly don’t think this was an altruistic and benign move from Hoyo’s part.
