A non-exhaustive list of topics that I haven’t posted about, but I do care about:
Azerite Armor
Feral Druids
Anchor Weed
Expulsom
Pruning
Class balance
M+ affixes
Tier sets
Encounter design
Utility
Gold missions
Paying a sub to play beta quality content
Navigating around the pyramid
Loot/reward structures
Being busy, or simply choosing not to post, is not the same as not caring. If I posted about everything I care about, I’d never get to actually play. Given how many island expeditions Method is running, I imagine that they are quite busy. And frankly, if I had to choose between posting on the forums or doing what I was passionate about (in their case, prepping for the world first race), I’d make the same choice.
I just happen to be in a situation where I have time for forum posting about guilds and playing the game. Not everyone has that luxury.
