Progression feels meaningless. It doesn’t really enable me to do anything that I haven’t done already. All it enables is scaling the numbers up, which is only interesting if you’re in it for the challenge itself i.e. you’re competitive to some degree.
If you want to explore Azeroth, that’s over in a couple of weeks, and then you’ve got nothing but boredom. That’s why the game explodes in popularity with every patch and then falls off a cliff about a month later. That’s why Blizzard gives us mounts for being subbed for 6 months at a time.
The truth is that, because of all the accessibility and easy-mode stuff going on, the game DOES NOT cater to casuals, ironically. It just unloads everything in weeks and then it runs out of steam.
