Now you are speaking the truth and that ain't allowed much better to scapegoat lfg than point out the real problem lack of content.
In mop we had 5 open world places to do things in added after launch thunder island, Dino island, landing zone Karasang wilds, battle field barrens and timeless island. We had one added in wod tanaan jungle. Think that says it all. Oh, and for an expansion that is raid or die we got one whole less raid tier. If that isn't shockingly less content I don't know what else to say and I didn't even mention scenarios.
