The Brewmaster artifact weapon quest was clearly designed with people having both flying and/or previously doing the Pandaria quest line. It expects you to travel to the Valley of Four Winds to complete the Monkey King’s riddles, however you have no way to fly there and following roads can lead you to Hozen controlled towns who are hostile even to Horde players, having not completed the Panaria quest lines.
This definitely needs a QoL update, similar to how LiLi allows players to fly using a vehicle during the Windwalker Artifact Weapon quest. Either a portal to the general area in Valley of the Four Winds, or some way to travel quicker. Also making it so you are not hostile to the Hozen as horde.
