Yes, I’m aware. But again, I’m not arguing writing (and roleplaying) aren’t subjective. I’m saying you can give feedback on writing that is rooted in more than “oh, I just like it this way.” I don’t want to pull the “I’m a professional editor at a publishing company” card, but it’s not like I’m saying this as some hobbyist enthusiast. My colleagues and I do give feedback to writers based on what the writer wants to achieve with their prose, and what techniques one could use to achieve that. And I assume so do you. It’s not just, “well, imo…”

It remains subjective, but I believe firmly there’s a difference between “I use long sentences because I like them” and “I used a long sentence here to build up the same sense of overstimulation the main character is experiencing from the constant barrage of sounds and flashes of light and voices and the clanging and banging of pots and pans and mice skittering over the floor as aunt Marie’s cackles with delight while a train’s lights flash in the rearview mirror.”

If someone asks, “Hey, how can I convey this character is being overstimulated?”, is the answer “Eh, that’s a matter of opinion”? Sure, there’s not one universal answer to that question, but knowing what you can do can help people develop the style that works for them.
