He then added, "There is another issue tangentially related to this discussion that I also would like to address: Many feel that it takes too long to level in the 60-80 range in particular, and that the combat pacing issues discussed here are just a piece of that larger problem. We agree – currently players are taking about 15% longer per level, on average, in that range as compared to before 60 or after 80. We’re in the process of assembling a set of changes that will smooth out the experience curve at level 60 and beyond, reducing the experience requirements for those levels."

Most of the time you spend leveling will involve questing and slaying monsters, but there’s also a lot of travel. Travel earns you little experience (you do gain a bit for discovering new areas), so it’s wise to keep travel to a minimum. The new level scaling system, which scales zones to your level within a preset range, helps with that. You can choose what zones you want to experience and stick with them until you finish their quests.
While Leveling your characters in BfA you'll also need to complete the new War Campaign quests in order to unlock world quests and the ability to venture to the other factions contintent. We cover all of this in our War Campaign guides and with out new Guide Tabs feature you can have both Leveling and War Campaign guides loaded at the same time to easily switch between them.

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.
