According to the WA devs, rumors are that there are less than 10 devs working in that division. And by the WA devs estimation, there is literally not enough time before Midnight releases to do everything that the collective addon authors have spent decades implementing.
It’s not about playing the game or not. I said this at the very beginning: Blizzard operates under a budget. Compared to 3rd party addon authors who did these as passion projects; operating under a time and financial budget means there are going to be cuts and things left out to meet deadlines.
Everything is going to be worse. That’s the point.
