O Metamagic ignora os componentes verbal e somático; o Feiticeiro não é obrigado a escolher

O fraseado "sem componentes somáticos ou verbais" é, na linguagem simples, interpretado como significando que ambos não são mais necessários.

Se o objetivo dessa metamagia forçar uma escolha de qual componente o Feiticeiro deveria ignorar, então deveria ter sido formulado de uma das seguintes maneiras:

Subtle Spell. When you cast a spell, you can spend 1 sorcery point to choose either one of the Verbal or Somatic Components. Whichever components you choose, you do not need to provide those components for this spell.
_{Stated as clearly as possible.}

Subtle Spell. When you cast a spell, you can spend 1 sorcery point to cast it without either the somatic components, or the verbal components.
_{Keeping the general phrasing, but with the comma doing heavy lifting.}

Subtle Spell. When you cast a spell, you can spend 1 sorcery point to cast it without the Verbal Components. Alternatively, you may instead cast the spell without the Somatic Components.
_{Calls more attention to the choice itself.}

Silent Spell. When you cast a spell, you can spend 1 sorcery point to cast it without the Verbal Components
Still Spell. When you cast a spell, you can spend 1 sorcery point to cast it without the Somatic Components
_{Splits them into different metamagics; would make it harder to gain additional metamagics though.}
