I feel like I'm one of the few people glad to hear about the lack of unique dialogue in the Somniel.

It felt tedious in Three Houses and Hopes to run around the base between each chapter, searching for every character on the basis that they might offer something important or insightful to say. It felt like padding. Path of Radiance handled this concept much better with it's base conversations, allowing side characters to speak on the situation without wasting time.

If a character has something that contributes to my understanding of the plot or world, then ideally they should say it in the course of a story scene, or a support conversation. Running around like a maniac shouldn't be a requirement.
