If you're not interested in collecting pets or something like that, and aren't a PvPer, I'm not sure what you're supposed to fill more than a couple of hours a day with in WoD. Raid nights aside, there just doesn't seem to be any character-improving content that's available "ad libitum." It's all gated behind a timewall or a daily allowance, or rewards toys and cosmetics. Once finished with heroics, which took a week, I can't see what I'm supposed to be doing. They took away the justice/valor grind, they essentially removed professions, and reputations no longer award anything useful. I can do my CM daily, I can roll my missions, and that's the extent of it.
