It's likely a strategy for Hoyo to boost "player engagement" for their shareholders by artificially increasing time spent logged into their games. CN gachas in general have this problem.

Take Hypergryph (Arknights devs): Characters in AK tend to ramble, turning would-be simple explanations into 15-minute monologues. Excess dialogue still persists in Endfield; NPCs needlessly explain the same concepts and situations multiple times through the story while compulsively glazing Endmin, a run-of-the-mill silent amnesiac MC. It hurts the pacing and artificially pads out its "play time".
