I don't know whether this fits in here perfectly, but...well I'll break here, 'cause intros are always boring...just like this one...so
Could it be possible, that Hitrating has no effect on Demoralizing Shout?
Today on the Vezax pull I wanted to apply it, but it missed 2 times in a row.
And I'm Hit capped, 7,04% over gear and 1% from Heroic Presence.
I also made a little Test, where I applied Demoralizing Shout 1000 times on a Heroic Training Dummy and missed 73 of them.
