War Mode, enabled and disabled in Stormwind, gives 15% bonus experience for quests and kills in any zone. whether you're a fan of pvp or not, this might be smart to turn on as Alliance starts on Kul'Tiras and the Horde are on Zandalar. Most horde are going to only be on our island for max level world quests. If you dont like PvP, my advice would be to turn Warmode on for the first few levels, then disable it around 112.
Something to keep in mind as well is that this will make enchanting materials more valuable, since it is likely most players will now simply scrap their boe greens instead of getting them disenchanted. Also redundant dungeon/raid gear can be scrapped rather than traded to the (guild) enchanter in the run. Less stuff gets disenchanted, meaning there will be less ecnhanting materials, meaning their value will rise. All the more reason to DE rather than scrap as an ecnhanter.
