No. Since at least WoD, the game is dangerously close to a lobby-based queue, which can be good for a MOBA or a FPS, but completely out of place in an RPG. There is no need whatsoever for further pushing the game that way.
One could even say that the various "borrowed power" systems of the last expansions were an attempt to let players obtain a modicum of player power by themselves, without the need for a premade group (i.e. the queue, especially for more casual people). Too bad that the medicine ended up being worse than the actual disease, but that'd be worth a separate thread.

To be fair, they are being encouraged by Blizz, who design the game for such a demographic first and foremost.
