Sorry to burst the bubble, but it’s been going on longer than that, hah.
Part of the issue is a lack of consistency; Blizzard doesn’t carry features forward, they scrap them in favor of new, untested things because that grabs headlines.
Island Expeditions, War Fronts, Artifact Weapons, Garrisons, Archaeology, etc.
Instead of improving upon these things and making them integral, well flashed out parts of the game - they leave them behind as relics of previous expansions.
I know some players like the “SHINY! NEW THINGS! LOOK!” mentality, where every expansion they get new races, classes, systems, w/e, but I’d really like depth, not breadth. When there is an abundance of really boring, poorly designed, likely to be discontinued or unfinished things, I lose interest.
I’d rather have a few core systems that never change, are well oiled, and highly regarded by players.
Give me an expansion where the company focuses on telling a genuinely well fleshed out narrative that doesn’t trash characters for the sake of rushing a contrived plot along. Put all the resources into producing tons of raids and dungeons and revamp the old world. Overhaul professions to be immersive and engaging and RELEVANT even in the old world. Create an artifact weapon/item system that we can upgrade over the course of future expansions.
Find ways to fix what is there already instead of throwing out new half baked crap.
