Hate to hurt your ego and all but both LFR and Flex raiding is real raiding.
Both are harder then raiding in Vanillia and most of TBC and harder then everything up to uld in wrath. So by you saying LFR and Flex is not real raiding you are also saying there was no real raids or raiders in Vanillia/TBC/Part of Wrath and I bet a lot of people would disagree with you on that.
