I don't think wiping in LFR is a bad thing. And you're right, more often than not LFR is harder than even heroic raiding, but that's just an unavoidable side effect of a match made raid with no quality control. And I think that's okay. Wiping is a part of both raiding and pugging.
If players want faster, easier, and more rewarding runs they should make the jump to normal mode raiding.
You change your stance more than Hilary Clinton. LFR takes nothing away from the game. Nothing. The art, the raid design, everything else is already in place to be used from normal+ modes. Your (current) issue is with Blizzard not adding anything else to the game and blaming LFR for it, when LFR has no effect on it.
