This is more of a question than a rant at this point, as I'm 9 months separated from the game as of writing this. This is also more in regards to how it pertains to M+ for the most part.
But are people really fine with how it currently is? I know people who exclusively play WoW can lose touch with fundamental design as they are sucked into its specific analytic/statistical design, and as they opt to no longer play other games since WoW demands such a heavy time investment, being what it is. I've seen little to no complaints regarding this, so I'm taking the default assumption that nobody in the WoW community cares or in fact actually likes the current setup.
Specifically, I'm talking about the fact that SL's Vault System massively changed how loot is rewarded in M+ dungeons from BfA to now. We went from a system where you could continuously run M+ dungeons for chance at great loot due to Titanforging and M+ loot being competitive to raid loot, to the current system that we have, where running M+ solely exists to add another slot to your Great Vault for increased loot choice quality.
My main issue with this is that I really like killing monsters and watching them drop quality loot. Currently, this is no longer possible with M+ as the mode does not reward competitive loot, but only serves a function of being an aggregator for your Vault rewards.
I would personally like to go back to enjoying seeing competitive loot drop in the dungeons themselves. Removing or redesigning the Vault System, however you go about it is required.
