As for Battle for Azeroth’s lack of new 120 talents, Hazzikostas explains it as a tough scenario. If the designers come up with three new abilities for rogue or death knights, those classes may not necessarily need three new abilities. Those abilities may be filler, or they may shore up a weakness in the class design and remove counterplay. That being said, Hazzikostas does agree that “it’s possible we’ve gone too far.”
For this farm we're taking it all the way back to eastern kingdoms. We're going to be killing the purespring elementals in the purespring cavern for the item essence of water. Essence of water is a semi-rare drop that goes for a shocking 252g per piece. The caveat is that it doesn't drop all too often, but is still worth the trouble. I wasn't getting TOO many of these, but I was still making bank with them. The essences are used to create the old-world illusions, so they do have some inherent value. Simply patrol the area and kill as many elementals as your heart desires. It's a really cool and fun farm that can be done on autopilot. Usually there is noone patrolling the spot.
With G'huun's threat eliminated, the Horde and Alliance return their focus to the war. While the Horde procures the Scepter of the Tides, a legendary artifact capable of controlling the seas, the Alliance dismantles a potential alliance between Sylvanas and the vampiric San'lyan Elves. The Alliance begins to gear up for a preemptive strike against Zandalar, with the goal of crippling the Golden Fleet before it can be used against the Alliance and driving a wedge between the Zandalari and the Horde.
Just before Battle for Azeroth goes live, you will want to log all of your characters out in the zone of Silithus so that you can acquire the quest to talk to Magni and obtain your Heart of Azeroth (refer to our Heart of Azeroth guide for more information about this item). This is the new artifact-type of piece of equipment that you will use for all of the Battle for Azeroth expansion. Once you acquire your permanent neck slot piece of equipment, get back to Stormwind or Orgrimmar to begin your scenario that leads into the introductory areas of Kul Tiras and Zandalar.
