Well you're got a looser definition of grind to include everything. Time gated stuff isn't the same as something you're active for. I know I'm not alone in wanting something where you've got to save X amount of stuff and it's not weekly restricted but still takes weeks just from the amount of grind to work through. It might be somewhat arbitrary but there should probably be something in that category in the first year of each expansion where you can work at your own pace, be rewarded with something good and not run out of casual content in less than 10 hours of each patch cycle.
