Don't like LFR? Don't use it.
Those of us who find a use of it (in my case, casually seeing where the story is heading and what the newest raids look like, at times a slight chance of randomly upgrading some slot thar was eluding me for awhile) give meaning to it, and you have no place calling for it's removal.
Doesn't matter whatever other stuff you think we should do instead. It's there, and we do it. That's all the reason blizzard needs to keep it.
