Update: The reason for less experience from gathering is due to how Blizzard revamped professions and broke them down by expansion. In order to get full exp from gathering you'll simply need to find a profession trainer for the relevant expansion. (WoD you just mine or herb the first one ypu come across and the game gives you a scroll for learning WoD gathering).
Sometimes that requires players to earn gear to give them greater powers that they haven’t yet unlocked. That sense of progression is at the center of what makes World of Warcraft great and so successful over the last 14 years. There should always be a balance between gaining gear and strength through lower-level content and taking on the hardest challenges the game has to offer. With Battle for Azeroth, Blizzard has missed the mark. Getting to elite status just requires grinding content that isn’t fun, instead of players demonstrating their skills.
Taking Herbalism and Mining as your two professions can be a lucrative way to level with the very stable and high prices of herbs and ore thus far in BfA. While rested, each mining and herbalism node will award nearly 4,000 experience points which makes it so that four to five herbalism or mining nodes is equivalent to one quest. If you have the Sky Golem mount for herbalism, you can pick herbs without losing mount speed. There are also enchantments for gloves that will increase the speed at which you can process the herbalism and mining nodes. These can be made rather easily by an enchanter and should be relatively inexpensive on the auction house. These enchants will pay for themselves with the time saved while herbing and mining. Remember to continue completing mining and herbalism quests while leveling up to increase the yield of each node making your herbalism and mining leveling experience exponentially more lucrative.
Disable alpha versions in your Curse client if you do not want multiple updates per day. Make sure you check main download preference as well as DBM's individual download preference. You could have primary method set to release and dbm still set to alpha. Right click on DBM itself in curse client addon list and set it to release/beta to avoid the daily updates.

“That’s the impetus behind everything, is to just make sure that players feel like things that they do in the game will have great consequences or great victories or whatever it’s going to be, right? Ultimately, our job is to create a world and environment and mechanics that support all that stuff. And however the players choose to make their choices is really up to them.”
“In searching for inspiration for how that might unfold, classic RTS roots felt like the perfect place to turn,” said Hazzikostas. He later explained that your first job will be to get your team's base fully-functional which will require you to gather resources such as "lumber or gold" to upgrade town halls. You'll also need to clear supply lines of foes in order to allow "peons to do their thing."
Skinning is the third gathering profession and it is very different from the other two. It works by skinning the dead bodies of animals with skins. You need to both kill the mob and then gather the body. Your main customers will be leatherworkers. Skinning in Legion is very good and gives a large amount of Blood of Sargeras. I suggest pairing this with a crafting profession that can unload a lot of bloods, like Alchemy or enchanting. For an overview of the best farming spots in Legion you can check out this guide by hikons or this one by WTBGold guides.
