Rationale of severe nerfing of Armor of Faith

[luc-j-bourhis]

I have just noticed that the revised spell has a fixed 10% damage reduction whereas the vanilla spell has 5% per 5 levels. I remember how powerful that vanilla spell was in BG2 when Thac0 starts to stop being relevant. But was it so powerful that it needed to be nerfed to such an extent? Removing any progression, especially. Not a bug report therefore, just trying to understand the rationale.

I reckon that it being percentage-based already counts as meaningful progression.

I understand your point. Another one I had forgotten about is the rounding. With 10% reduction, a damage of 4 should be reduced by 0.4 to 3.6 but it is rounded own to 3, making it a 25% reduction in fact! For illustration, let's compute the average damage of a greatsword (1D10). I spare you the arithmetic! Without damage reduction: 5.5. With Armor of Faith from SR: 4.5. That's nearly 20% actually. I am wondering whether that was not part of the rationale actually.
