Well then you completely misunderstand me. The fact the the GMs (and I'm not even an active player right now let alone a GM) need to recruit players like that to clear Mythic content at a reasonable rate is the fault of Blizzard. That is the point I'm trying to make. I hate when people blame GMs for adopting the standards required to clear the content they're trying to clear. Those standards are pretty much set by Blizzard when they design the game. Blizzard's design is stupid, unfair, and goes against the spirit of competition this xpac when it comes to raiding... especially high end raiding.
Raiding was great in the xpacs you mentioned (although I exclude DS from that "great" complement)!
