Eh some of these factors are not necessarily down the state of this game, but the state of other games at the time. E.g., the player count just prior to EW had a lot to do with the WoW exodus, and some of the streamers from that side that it attracted, just as much as what it did with the actual state of this game. I would argue a large drop in the numbers was also partially down to this.

I am not saying it is the only reason. But it is a pretty big reason.
