I’d like to start off by stating the obvious, this is an opinion. You’re entitled to yours, but let me explain to you why I’ve mine.
It starts with that first word, Reduce. The removal of artifacts, the restructuring of leveling and the streamlining of class gameplay has gone to great lengths to decrease the perceived ‘bloat’. These go hand in hand with measures taken that nerfed or otherwise dismantled methods of gaining gold that were deemed ‘harmful’ to the token. Now that leveling and even gameplay itself can be given a dollar value, it will be Reduced to the bare minimum requirements for a consumer product. It's a bit shameless and underhanded, but rather an inevitability of Blizzard's endless goal to appeal to efficiency among their players (even though they still can't manage to fix their own management problems circa end of expansion content droughts.)
The second word, Reuse, outlines their uncanny ability to take themes, plots and narrative structure not only from other cultures and media, but from their own. Case and point, the faction war. Yet another expansion with a story entirely focused on the conflict between the Alliance and the Horde. They call it a persistent theme. I call it an easy scapegoat to reuse the exact same elements and plots over and over again for maximum effect, just change the names of the characters and the plot devices. Perhaps there are new stories to tell, small grains of 'new' among the constant Reuse of themes already exploited and experienced over and over, as if this version is going to attract new people. Though, this Reuse doesn’t even begin to touch upon the elements they are pulling from previous expansions with a slightly new spin.
For that, we move onto Recycle. The bulk of Battle for Azeroth’s problems. But first, a history lesson: In Blizzard’s desperation to refine their systems to an acceptable state in which their game can have meaningful progression while also maintaining profitability, they discovered the largest and most expensive department by and large was the Art and Animation team. People wonder why WoD was a shitty expansion? Look at the graphical quality increase of literally everything from the start of MoP (logically when they would have started working on WoD) and the launch of WoD. They remade every single race into a universal skeleton rig, the graphical quality of the zones, sky boxes, enemy models, enemy animations all of it doubled in quality. I imagine their art team spent overnights for months trying to make it even work. They put literally everything they had into WoD’s graphical superiority keeping players (Not raiders) subscribed forgetting non-raid gameplay entirely into what resulted in objectively the worst expansion the games ever had.
What does this have to do with Battle for Azeroth? Everything, actually. Everything from Allied Races to Warfronts to Azerite gear. They are recycled systems of the last two expansions with shiny, new names on them and new selling points. Except it’s not really new. The Allied races are the same races we have had for a decade with alterations and changes pitched to be sold under a grind for kickstarting the expansion they’re being released in. Warfronts are reused Garrison assets in a reused RTS format in various reused zones across the game. Sure it’s inclusive, but is it really that interesting? Azerite is literally 3 different Legion systems tossed into one and shamelessly so, while also somehow providing less overall progression and customization than what the Netherlight Crucible itself got us. Even the little randomly generated islands they will be having us go to is reminiscent of both the Scenario and the Legion Assault systems.
In short, Battle for Azeroth and it’s alpha have proven one thing to me: This is Blizzard’s design direction. They are looking to monetize what they have already created rather than creating anything new or interesting. This is what they spent the entirety of Legion coming up with next, and it’s not that impressive.
There’s still time to refine it, but I’m calling this expansion for what it is: A second Warlords with an obsessive focus on selling what Warlords failed to sell in their foolish endeavor to appeal to raiders alone.
