You're just a hater who wants to see Blizzard explicitly say "we failed, BFA sucked" just to have your feelings validated.
They know they failed, they don't need to scream it on the rooftop, you just see them as the enemy when they are not. They're just human beings doing the best they can at the job they have and if that's not good enough for you, you are free to go shop anywhere else. You are not entitled to an apology from them just to make you hard.
They know that at this point they can't make enough changes in a patch to really make people change their mind. They need something gigantic to really change people's perception of the game and that can only happen in an xpack. So acting like 8.2 will change everything is a waste of time and a lie, saying they will make awesome changes in the future is also a waste of time because no one gives a shit unless they actually see it in action and of course they won't have anything to show for a very long time.
This is just a case of take a break, go outside, wait to see what's in store for the next xpack. This is WoW, it's one game amonst millions, it's not a religion or a lifestyle, just a timesink like all other entertainment, you can go do anything else really, it's the smallest deal ever.
