It seems as if they're trying to make "scenarios" the new heroics. I honestly don't even know how many heroics are in MoP without thinking about it. They're adding four new scenarios and now introducing "Heroic" scenarios so people who are complaining about LFR Loot can get loot via these heroic scenarios.
Maybe I'm just weird but I enjoyed when new loot adequate heroics would come out, it was fun farming them. Plus, at least in a 5 man heroic for new gear, 1/3 of your DPS isn't AFK :\ as it's pretty noticeable if someone is AFK in a 5 man.
Maybe I'm missing one but to my knowledge, here's all the MoP heroics
Gate Of The Setting Sun
Temple Of The Jade Serpent
Seige Of Something Temple
Burning Crusade Heroics
I'm honestly not going to be surprised if they push out the whole idea of "Heroic Dungeons" and move towards scenarios instead.
