I disagree also. It has been my experience that the Priority queue is only
used during periods of congestion on the network. I've also referred back
to some of my training material and it states the same.

I disagree.
We use LLQ in our environment and unless I have congestion in the network I
do not see packets go across the priority queue. If it was in use all of the
time I would see packets in the debug output for the priority queue
continually go up.
