I took that to be an argument that, as far as CaGI is concerned, it has inherent features that impede immersion. If your only claim is that some people can't immerse while using it, that is obviously true. But @Manbearcat (I think) once posted about a friend of his who couldn't play his mage unless rolling red dice for fireball and white dice for ice storm. No interesting generalisation can be drawn from those preferences to general properties or features of dice design and dice mechanics!
I did. He literally had to drive 1.5 hours (thus shortening our sessions by 40 %) back to his place to retrieve them before we could play. A curious fellow but not unrepresentative of the strange attachments to rituals and legacy arrangements for the sake of their "immersive properties" that plenty of D&D gamers.
I think I was posting about the unified mechanical arrangement of powers (arcane spells, primal evocations, divine prayers, and martial exploits) and how that (oddly) contributed to people actually feeling that "fighters cast spells". The aesthetic of the framework outlining the mechanical resolution of any ability has nothing to do with the game world itself. Nonetheless, just reading those entries has some jarring effect on some people's ability to immerse at the table during play. I don't understand it and I've never heard it explained in a way that makes sense but its nonetheless true. From my recollection, the colored dice anecdote reminded me of that.
