From my understanding, the world boss is always there when your faction controls the Warfront. Like other world bosses you can only get gear from him once a week. There are other world bosses in the zones outside the warfront and 1 spawns a week just like Legion. I’m not 100% sure that the warfront will be available on launch but I have yet to read anything that says otherwise. The quest also reset once a week as well. Think of Warfronts like old Tol-Barad
First off, there is no reason to ignore the war Campaign, you need to do them to unlock world quest. Beside that, the way scaling works, war campaigns are easyer to do while leveling then at 120. Everything becomes alittel harder at 120, untill you get some gear, because of them scaling levels. Also, i did my leveling on a demon hunter in about 8-9 hours. I think i know what youtube video you talked about, and i strongly dissagree with him. One thing tho, total xp needed was buffed with 15% that in worse case would make me take 10hours, the way i did it.
Fully rested experience (this is the blue color your experience bar takes instead of purple) grants 200% more experience per kill. Quest experience does not work the same as mob experience. Instead of just using the rested bonus, quest experience pushes the bar further upwards extending the rested bonus. Say if half your experience bar is blue. If you turn in 10 quests all at one the normal experience from them all could boost a character a full level. Unlike mobs where the experience gain will use up said bonus - the quests merely 'push' the bar further. Doing this could net you a level and still have the 200% bonus for mob kills applying to milk the rest bonus.
“We are seeing the same sort of discrepancies that folks in this thread and others have pointed out,” said Hazzikostas. “But we still have yet to pinpoint the exact aspect of scaling that we failed to account for. We want to understand why the numbers are off and fix the underlying cause: Were stats on gear reduced too much? Some aspect of creature armor or other combat calculations? Are our baseline values accurate, but the shape of the scaling curve wrong such that it’s particularly far off the mark in the 60-80 range?
Some people have made arguments that quest blues can sometimes be more powerful than heirlooms, especially with sockets. I'm not convinced. The simple fact that you never have to even look at quest rewards will save a non-insignificant amount of time over the course of leveling. Also of consideration is the value of enchanted gear never having to be re-enchanted.
Getting reputation for the new factions is going to be beneficial in different ways. Earning reputation towards the factions is going to help you unlock Pathfinder in Kul'Tiras and Zandalari. Pathfinder is nothing new so i decided to include it in here. Pathfinder will give your character increased mount speed and its account wide. Also gaining reputation will allow your character to buy gear, from a vendor, equal to Heroic dungeon quality.
NOTE: It is VERY important to not vendor any equipment you pick up. You will be deconstructing all of your gear for resources that will help you in the Warfronts to be fought! Deconstructing, or scrapping, your gear will be done using the Scrap-o-Matic 1000 if you are Alliance and the Shred-Master Mk1 if you are Horde. This works the same as the way the Obliterum Forge worked in Legion. The scrapping feature can be used on all Battle for Azeroth equipment found, not just craftable equipment, so save everything you acquire for the scrapper! Before we get started, keep in mind some of the tips below that can speed up your leveling process!
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.
“I think [the levelling experience] is a pretty hotly debated topic internally, about how to handle that,” Dawson said in a recent interview with Gamesindustry.biz. “I think we recognize that we’re not giving new players as good an experience as we can, and we do want to focus on how to make that experience better. There’s 15 years of content that people should have the option to do if they want to, but we also want the ability for players to play with their friends quickly. That’s why we developed things like the boost [which automatically raises one character to an appropriate level for the current expansion], which you get if you purchase the game itself. The scaling tech was also a way to help us do that, and you can sort of choose your own path through expansions and story content.”
EXCEPTION: If you have Mining and only use Jewelcrafting to craft stone statues (for additional in-combat healing), then this may be a useful tradeskill. However, like Engineering above, it should not be a leveling focus and should only be used to assist with power leveling. Doing any more than this will become costly and should not be undertaken during the power-leveling process.
I remember time when I was at teenage and I used to spend real money for wow gold from some suspicious "hacker" site from China or Korean what ever(note: I didnt spend much). And now I have realized how foolishly I did even I didnt about real money problems in there. Now that I have grown up I have also realized that I was one of those that caused playing problems for those young boys, that they had to play like 24/7 to farm gold for us lazy people.
In my opinion, Zygor makes the best WoW leveling guides. They have been around for more than 10 years, which shows their commitment to maintaining and updating their guides to provide you with an optimized leveling path for any class and race, whether it’s Horde or Alliance. Zygor is an addon that includes a waypoint arrow and a separate window with instructions that, taken together, show you step-by-step how to level your character to 120, FAST. You’ll know exactly what to do at all times. It’s also very easy to jump in at any level; you don’t have to start exactly at level 1 or 110 or anything. It’s a bit more expensive than the other options, but I’d say it’s definitely worth it.
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.
