An idea for stronger use of "dominion"

[onomastikon]

I would like to see the religious aspect (dominion) play a stronger role; I like the idea that troops get +1 / -1 morale depending on dominion, but I find that not enough. Would you like / dislike the idea of having additional bonuses for higher dominion, such as a percent chance of scoring double damage or a "natural 6" (on the d6 roll) for combat damage or spell effects when cast / used in higher dominions, such as:

+1 dom = 0%
+2 dom = 1%
+3 dom = 2%
+4 dom = 4%
+5 dom = 6%
+6 dom = 8%
+7 dom = 11%
+8 dom = 14%
etc.

or something similar.
what do you think?
