Mentioned first, perhaps, but as: "heroes." while the MC is: "Amazing HEALER-SAMA!"
You found a nice way to justify it, but as far as I see it -- it's because the author only bothered writing story-arcs for the healer, and did almost nothing for the heroes...So, obviously, they have nothing to be recognized for, to share, or to talk about. The fact that the weakness of the first enemy boss, was precisely healing magic, shows this. The heroes take the sidebar while the author focuses on glorifying healers.
As I said, I get it, this is a story about healers, but it's odd how the heroes feel hollow and pathetic, and might as well not even be in the story.
