Focus Spells are “easier to use” spells that, relative to full slotted spells, should be easier to use. Since spell slots moved from “wait until the adventuring day is over” to “have a pause during exploration”, it seemed appropriate to move focus points from “have a pause during exploration” to something easier, meaning “during combat.”
Since it burns actions to do nothing but recover a single focus point, having it be as complex as casting a fireball (2-A) seemed excessive. So, 1-A is where I landed.
Based on the sorc getting a flat boost in PC2 I think someone at pazio shares your critique.
Would the boost perhaps make more sense as a wizard class boost or arcane theory?
