That quote is talking about BiS and you're talking about, mostly, welfare epics. Are you saying welfare epics are BiS? I think you took that quote way out of, well, not context so much as out of the words he said and into other, imaginary, words you wished he said.
Gonna touch on one point though: LFD made groups harder to make? Seeing as its basically just an automation tool that extends the pool of players to include other servers I have a hard time believing you. I don't remember carrying people either because they were so easy and the mistakes you could make were almost always fatal; it isn't like there were enrage timers left and right.
