Fair enough.
Holy Ardor grants you a "Critical Hit" if you roll doubles.
You normally can't have a "Critical Hit" unless you also "Hit." Holy Ardor, however, bypasses this requirement.
So, either you hit (implied by the fact that scored a critical hit) or you scored a critical hit but missed, which seems like a contradiction in terms and must not be true.
Therefore, when you "score a critical hit" you must have also "hit."
Yes, its a bit weird and could have be written better, as no matter what way you read this power you have to make some assumptions, and we should not have to do that.
But it remains that I make no assumptions in my reading. Stick to what the rules say and not what you want to read into them.
So, either you hit (implied by the fact that scored a critical hit) or you scored a critical hit but missed, which seems like a contradiction in terms and must not be true.
The bold part is what matters. You have assumed that because it seems like a contradiction in terms that "it must not be true".
To me it is quite clear that the rules on "Hit" and the rules on "Critical Hit" are two separate rules that sometimes interact with each other. All this really proves is that Holy Ardor is no better than any other crit range power such as the Dagger Master feature because they can "score a critical" on an 18 and "Miss" as well. Ok...it also proves that the permissive language of "can score a critical hit" doesn't matter which I (and several others) have argued all along.
