Great story telling! First time ever that I am so invested in an expac story. I read every quest text, and it hits me hard in the feels especially Ardeanweald. I like that there are four covenants to choose from, and most of zones are so good that its hard to choose. The visuals of surrounding, the setting of each zone, the music, and even the zone character leaders are all so well done. I have to choose between the best storyline, or the best looking mounts. And I like that extra mounts are easily collectible now.
Another thing I like is that the quests given are mostly focused on main storyline, and there are lesser side quests compared to bfa, even if its sidequests mostly are to explain deeper on zones. So there is good balance between main and side quests, and the flow of story is well received.
So far, the whole gameplay experience is very smooth, no lagness, no bugs encountered.
