I hate grind, but I used to enjoy just playing D2 weekly, way beyond the weekly content.

Then they decided that literally everything needed to be a slog, and that being overpowered was bad, and they ruined my fun. I went from 80 hr weeks (I know this isn't healthy) to 1 hour weeks over the course of a couple seasons. I still spent a lot of time after the launch of the latest DLC, but after that was done, and they upped the base difficulty by removing the effect of levels on almost all base content, I struggled to stay engaged. This season, I just gave up. I've got like 15 levels, when I usually have 200-300 in the battle pass.

I'm not saying they don't have a grind problem, too, but it wasn't what killed it for me.
