So I managed to complete my seventh class order hall campaign this morning. They've all been pretty interesting as content goes, and I'm not sure that I could pick one that I've liked more than others. But it's been pretty interesting working through all of them.
I wasn't a big fan of having to grind out the various dungeons on the demon hunter campaign (as I understand it, that also happens in the mage campaign, which I haven't done yet). My main issue there is I never really did decide if I preferred playing as tank or dps. I was questing mostly as tank, so I wasn't doing real well as dps in those dungeons.
My monk is still sitting at level 103, so I've got a ways to go at this point before I'm in a position to start doing much on his order hall campaign. The windwalker monk has been fun so far, but I'm not in a huge hurry to finish leveling him. I don't particularly see that as a class that I'm likely to do much beyond finishing the order hall campaign, much like the demon hunter.
I also managed to fill out the 35th trait on my weapon on the warlock, and I'm getting close to a full weapon on the hunter. Rather than continuing to fill up the warlock destruction artifact, I decided to switch over and start putting points into the affliction weapon. So we'll see how that goes.
Beyond that, with Nighthold opening today, the quest to upgrade your legendary is out, so it's important to grab that before you open any emissary chests, because the quest items can drop from those chests.
At some point, I also need to go back and work on the leatherworking and alchemy profession quests as well.
