No, it cant be called an Heroic, because what youd escribed doesnt have the characteristics of heroics.
And no, i didnt miss wehere you were saying you werent talking about daileis, and yes, Blizzard could have done plenty of things, but they did what they launched for 5.2, not some imagine zone event.
What i am asking is for Dungeons. What they did was create a new questing zone. Completely different things that you insist in comparing. Apples =/= oranges.
Blizzard did nothing new here. Hell, even they sold this as a new Isle of Queldanas patch. Its THAT new (meaning nothing new of course).
