Kalli, my friend, I don’t mean to offend you personally, but you cannot be this dense my lady.
Removing the systems would be contentious, to be sure; but it would also force people to work together to accomplish objectives in the game… which is the very source of a community in the first place.
Removing the system doesn’t restrict access to anyone; this is a fallacy, easily disproven by the fact that you don’t need an LFD or LFR group to complete any of that content. You and four other people can do a Normal right now, without queuing.
LFD and LFR aren’t required, but are harmful.
If you still feel differently then that’s that. We’ll agree to disagree. Not much to do. I just feel you are assuming a great deal of unsubstantiated motivations about others who disagree with you.
