Enchants. I honestly wasn't 100% certain which enchants were best, since scaling has screwed up a lot of things. IMO, just pick the enchant for each armor slot that has the highest bonus without level restrictions. The exception is that you'll definitely want Mark of the Hidden Satyr for your neck piece, and probably Elemental Force for your weapon. Both of these proc consistently and strongly across all levels.
The zone you start in isn't under your control, in as much as it's pre-selected for you based on your race. But for leveling purposes we want to make scaling work for us as much as possible. That means sticking to the lower level zones. Even though scaling will increase the level of the quests and mobs in those zones, the layout and design of them is built for a player with no mount. So you'll blaze through them and gain more exp/hour than higher level zones which assume you DO have a mount. 

As you continue to push through end-game content and you raise your reputations with various groups, you unlock more quests that send you to the opposing faction's continent where you generally try to mess with them, gather intel on their movements, and, of course, kill a whole bunch of them. These quest lines are fun, but generally pretty short and don't actually propel you through much of the three opposing zones.
The community was apparently frustrated with Blizzard for a lack of communication concerning the issue, but it looks like that was due to the fact that their heads were down as they worked to understand the problem. It was explained that they didn't want to just roll out a quick bandage, as that would likely cause unforeseen issues down the road. Instead, they're crunching the numbers and digging into the code in the hopes of discovering a legitimate source of the problem.
Most BfA Alchemy recipes have 3 ranks. Rank 2 reduce the materials required to create a recipe, and Rank 3 have a chance to create multiple potions/flask etc. Higher rank recipes also give skill points much longer, so it will be a lot cheaper to level Alchemy if you first get Revered with the new BfA factions, because you can use cheaper recipes for longer.

The Escalation patch has introduced several new scenarios with respective heroic modes that provide shiny new loot. It is still too early to predict which of these will demand the highest prices at the auction house or AH, since it can take weeks for players to work through the content and determine the value of the new drops compared to the existing items. Many expect the rarest and most prized drops to start commanding handsome prices starting June, so just keep your eyes peeled for popular WTB requests in general chat and high-selling items at the AH.
Lastly: The zone order I recommend for Horde is Vol’dun- Zuldazar- Nazmir. Vol’dun is definitely the most challenging of the bunch and having the use of your Legion gear and leggos will smooth this zone out. Nazmir is the easiest of the bunch which is nice when things start to get a little grindy past 116. For Alliance, I recommend Drustvar- TS- Stormsong. Same logic as the Horde side, in my opinion Drustvar is the hardest and Stormsong is the easiest for when it gets grindy. I would recommend you waiting to do any of the War Campaign until you are capped because it just takes you out of the way. I also recommend not killing a single rare mob or picking up a single treasure because in my experience it is just not even remotely worth it. The gear scales up on the rare mobs so its smarter to keep them till 120 anyways. After you are done leveling, I do recommend taking the time to do all the quest at the Faction Outpost in your enemy territory. They do provide rep for the Honorbound which helps. Most of them are quite easy. If you do not level in Warmode, you will usually hit 114 from your first zone, 117 from your second, and cap 120 about 2/3 in your final zone.
In addition to questing and running dungeons in the Broken Isles, players should also remember to visit their class hall, which is like the garrisons from Draenor, but themed around your character’s class.The quest lines in your hall provide valuable experience and open up important features, like artifact weapon upgrades, that will drastically up your character’s power.
World of Warcraft Gold (US) is a currency used in the US server as a medium of trade. WoW Gold, items are rewarded after killing the enemies. WoW gold is a limited resource and is hard to come by even though gold can be earned by various ways. It is still time intensive for any player to gather the gold needed to get better gears which make advancing easier. Because of the enormous need for WoW Gold, it has attracted many exploiters such as dupers and gold farmers. Arguing that they ruin other people's experience and enjoyment of the game, Blizzard has put up a strong fight to combat these exploiters by banning large number of accounts involved in the activities. However, there are as many players who would not want to invest their time and are willing to pay the extra money to get through the game. Generally, the price of WoW Gold in the EU servers are more expensive than those in the US.
