I'm starting a new campaign and for the first time ever and I'm trying a Psychic spell caster (Psychic, specifically.)
My GM is pretty adamant that the metamagic Still Spell and Silent Spell exist for a reason, and that Thought/Emotion components are clearly detectable in the same way – and what's more, that with Deceitful & Cunning Caster, I take the same -4 penalty to Bluff attempts for Thought/Emotion.
Is psychic casting (with Thought/Emotion components) detectable in the same way as Somatic/Verbal components?
I follow his concerns about balance, and he's got thousands of hours more under his belt in PF than I do, but I feel like this is the point with Psychic casting. It's baked into the classes for a reason, and RAW/RAI is being ignored because he's worried about balance.
Am I in the wrong, or am I misunderstanding anything about Psychic casting?
