I don't disagree with much of what you write, actually. I never liked LFR, and did find matchmade groups of any size to be disappointing on an interpersonal level most of the time. I think Wrath's relative ease worked well with it (and the whiteknucklers, exposing the weakness of the system, were ICC 5-mans). My point is just that it was gangbusters all the way to December 7, 2010.
