Casual myself here. I always find something to do. The highest content I go into is a mythic dungeon or low key, and that’s okay with me. Lfr is a huge time consuming waste of time at the moment, so I avoid that. I mostly farm for tmog and mounts. This game really appeals to the collectionist part of me, and luckily there is endless things to collect! I think you need to expand your view of things you can actually do as a casual player
