If you think they design the raid for LFR and then add more stuff to the harder levels then you'd be mistaken. The reason they call it "very hard" even though that's actually the base game is so they don't make people feel bad for not playing it the way that they wanted it to be played.
Now, in WoW's case I believe the base game is heroic mode and mythic is extra hard just like when you play Halo and you have weenie mode, casual mode, real mode, hardcore mode. They made the game tuned to the second hardest difficulty but added an extra one that's even harder because they wanted to give people a challenge. They also didn't call the base game normal either. It was "Easy, Normal, Heroic, Legendary" with Heroic even being cited as "the way Halo is meant to be played."
