Ok, say a focused practitioner has taken both channeling and/or ritual.
If the player "bought up" from channeling to evocation, does the character still qualify as a FP? There is no single template that requires only evocation. My thought is yes, as channeling is a specific form of evocation, but that the character could buy up to evocation, but not become a full evoker until a major milestone (as technically this is "acquiring a new power" going from a single type to a broad type). I'm thinking the same with Thaumaturgy/ritual as well and having to change high concept.
Thoughts?
