It comes with a detection system for quest which monitors your previous actions and makes improvements based on them. A directional arrow that appears on the screen will indicate the best direction. It is fully automated hence saves you the trouble of having to click when moving to the next level. By following the guide you will require fewer than 7 game days to move from 1 to 80. You can begin from mid-level and let the guide lead you through the next levels.

Assassination Rogues make use of damage-over-time attacks to do the majority of their damage. This makes them incredibly strong single target damage dealers. On top of that, Assassination Rogues have many defensive abilities that allow them to survive a wide range of potential encounters as well as mechanics within raids and dungeons. Their weakest point is the lack of multi-target damage abilities. Their rotation is also very cooldown heavy and is only really effective at dealing with single target encounters.
The neutral auction house can become one of your best friends. Other players are constantly checking both factions' auction houses to find an appropriate price for the good they demand. Often times, goods are cheaper on the alliance because they have more people, thus, the supply increases as demand decreases and price goes down. If you are horde, feel free to transfer gold to your alliance toon through the neutral auction house in order to buy them item and bring it back to the horde side where it is more expensive. The 15%, as of patch 3.3.3 (down from 30%) is well worth the extra 50% or more you can easily make on one item alone. Blizzard decreased the neutral cut for a reason to 15%, that reason is to get trade facilitated between the horde and alliance. Make sure you take advantage of this! Tips when trading between factions:
Nov 6 Pet battle advice and leveling class Hi all. Been doing pet battling so far. I like it a lot. But I am not getting very much experience for my class Does the experience get better later on? I am a level 2 orc shaman with about 9 level 3 pets. I will keep leveling my pets but the experience feels very bad for my shaman levels. Any pet battle advice is welcome. Thanks. Also I have a few heirlooms and some gold.Goldshaman4 Nov 6
Good question. Me personally, when I use a new strat from somebody else, I always read thru the strat, and in the case I really need to level some pet, I then (likely) exclude strats that are mentioning things like “RNG”, “risk”, etc. But: I’m always happy (when using a new strat) when I see some detailed infos, so that I can estimate what is going to happen. But YMMV.

In BfA you can also craft weapons, including Bows. While I don’t have any personal experience I expect the item level 300/310 gear will sell as well as it does for blacksmithing. You can also utilize the level 110 bracers in the scrapper to generate expulsom. This may be cheaper than linen on some realms, but it heavily depends on Blood-stained bone prices.

A common mistake of new players is to upgrade their gear at every opportunity, paying for a new piece even if it will only add one or two new stat points over an existing item. Likewise, investing in headgear, neckwear, trinkets, and rings at the earliest available levels can also consume valuable cash. While it might seem foolish to leave an available slot empty, you will eventually find something to fill it. Blizzard will see to it via the quest rewards you'll get along the way. In the mean time, the 1 or more you save will serve you well if you invest it wisely. The bottom line is that one can easily level all the way to the maximum relying on just quest/drop greens. The gear you get from regular questing can help you perform well in dungeons, which gets you even better equipment. 

While leveling, try to make use of the new Battle of Azeroth experience gem, Insightful Rubellite, which gives you +5% experience. Equipping one of these requires a socket in your gear, so try to hold on to a piece of Legion gear with a socket or acquire one of the Legion Legendary rings since every class has one. Each of the rings includes a socket. You can acquire one of these rings rather easily by doing World Quests in Legion zones and acquiring 1,000 Wakening Essences that can be used to purchase a legendary ring in the Legion version of Dalaran.
As late as possible. Early on, you’ll want to follow the missions in Battle for Azeroth right up until you get the option to send a follower on a two-hour long quest. As soon as you get there, stop doing the War Campaign missions. You can come back to them once you have reached something like 119 and a half and finish leveling with those if you want. If you don’t use these missions to cap off your leveling journey, then they’re the first thing you’ll want to do once you reach max level.
Was doing it at 52 on my lightforged paladin and it was easily the slowest zone out of the ones I'd done. Granted, I didn't have War Mode on so I didn't have any PVP talents, but it felt like about 40% of my time was spent waiting around for respawns or wandering around looking for mobs to kill to get a quest item that had like a 5% drop rate. Maybe I just got unlucky but I definitely won't be going to that zone again for future heritage armor runs.
Then 8.0 came along and turned everything on its head. Most of the techniques and shortcuts discovered, after 7.3.5 introduced scaling, were nerfed into oblivion. Many of the old techniques were confirmed by myself, first hand, to no longer work. I'm hoping that this thread can serve a similar purpose as the old thread, and gather as much data as possible on the fastest methods under the new system, and facilitate as many different perspectives and opinions on speed leveling with constructive discussion. I've just finished leveling to 110 under 8.1 with the exp curve.
