I can't get faith and conviction over 8 (or 8.8 but it rounds down) deflection even with DispositionAddPoints to get 4/4 in my favored disposition, and I had to level up after raising them to get that to work.
Is this a bug or a nerf? 8.8 seems a weird number to cap at so it feels like a bug. It used to cap at +11 deflection +22 fort/ref/will.
