It’ll also potentially inform what you can cast when - can’t perform somatic components of your hands are bound, can’t perform verbal components in a zone of silence, can’t perform material components if you don’t have the materials.Yea, just read those comments. Looks like component will be more of a hook to hang class distinctions on, then (like the bard with the violin example). Makes sense.
I do hope they list some materials for spells within material components. I know they rarely come up, but they’re a nice dash of flavor.
