So as the title suggests, the scenario is that Blizz has tasked you with creating a class specific questline. Can be short and intense, or long and involved. I tried asking this question a while back, but with the way some of the questlines have panned out in Legion, maybe there'll be a better response this time around. I'll get the ball rolling:
My questline is for Hunters. As rugged wilderness dwellers reliant on living in harmony with the beasts of the land, we seek ways to more easily traverse the wilds. My quest chain sets us on a path to seek ancient knowledge of legendary hunters of the past, sending us all over Azeroth, Outland, and Draenor. We seek out the final resting places of these legendary hunters, who will pass on their knowledge if we can prove ourselves worthy by overcoming a trial. Each trial will involve the tracking and defeat of either a particularly vicious beast, or a nemesis of the deceased hunter, and returning with a trophy as proof of success. Each trial will require different aspects of the hunters toolkit to overcome, maybe even requiring talent changes to survive or neutralise various hazards. The final step in the questline involves acquiring the blessings of the Wild Gods, with the final reward being granted the ability to cast Wild Mount. Instead of a mount from your list, casting Wild Mount out in the open summons an area specific beast that serves as your mount until you dismount, at which point, the beast fades back into the wild. This would be an instant cast, along the same lines as Druids shape shift forms, and if cast in the air, results in the summoning of a flying beast (in areas where flight is enabled/unlocked).
I think it'd be pretty cool, and fitting with the class fantasy, as well as give non permanent access to some unique mounts. For those who like to immerse themselves in both class and questing area, it'd add just a little extra flavour to the overall feel.
