I'd like a spell-less start with a few options to add spellcasting via subclass. Some of the options could have a built-in minor version of Subtle Spell, so while you're mechanically casting a spell, it's easy to reflavor.
Aragorn's use of athelas would be an example: he said a few words, made a few motions, and used an object to cast something like Cure Wounds, but he wasn't wizarding it up and creating a lightshow. Many GMs would enjoy letting a ranger reflavor components like that, but then a full-time caster will want to use the same trick to stealth-Dominate or Fireball the queen while she's holding court. I'd rather have something that justifies the ability in the first case while not letting it apply to the combat and mind-control spells.
