Midnight is here, what's the verdict?

So midnight is out, and I've seen people say it's looking like potential best expac in a while.

As someone on the outside, not playing just loitering and seeing what's going on, I'm curious.

Is this the best expac in while? Is it just another one on the list, or is it the one to bring everyone back?

Asking as I'm curious about coming back. Not played in i think, 5 years? Maybe 4.
