Pick druid, paladin or monk. Get heirlooms if you can. Grind mobs until level 5 - 6. Start doing the easy "just kill these mobs outside town" quests until 15. Queue rdf as every role and do every dungeon you can (with heirlooms you could probably solo the dungeons) while you travel to higher lever zones. Keep doing the simplest quests while you're waiting for rdf (which shouldn't be long). I leveled a druid to 100 once doing this in maybe a day /played, but he was also rested for most of the process.
Fifth: World Quest are back and are still important for leveling your Heart of Azeroth and gaining rep. I do recommend you do these in Warmode for the additional bonuses but if you don’t like PvP I would at least suggest doing a clear of all the quest that don’t give AP in Normal mode then going back and clearing the ones that do give AP in Warmode for the bonus. Emissaries are back and work the same way though it is very important to hold off on any emissary quest that gives you gear until you are at least 310 item level. Once you hit 310 item level, the reward jumps to 340 loot instead of 325? (its somewhere around that area). Try to delay these the best you can, but don’t risk missing out on free loot.
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.
Players have ever thought that Warfront are one of the most important and anticipated feature. Warfronts are a 20-man, PvE, large-scale cooperative mode meant to represent the large-scale war on the homefront, as members of each faction fight for control of a location critical to their war efforts. But now the Warfronts seem less worth players' attention.

I personally like it but I have healed for 11 years. This will actually be the first xpac where I actually main a DPS (UDK) ever in my history of WoW. The thing I actually really like about pally is they have an Azerite trait that gives the whole group a mini stampeding roar whenever you use golden pony. That is a great utility for a class to have. If I decide to not do UDK I will be doing HPal because it’s the one healer I have never mained.

As you're leveling, I generally recommend you just follow the natural flow of the progression through each zone. They're laid out fairly reasonably. But don't be afraid to hop around, especially if you're near a quest objective. You shouldn't actually need ALL of the zones listed to reach 62. Pick the ones you like best. It's much more important to simply be as focused as possible and flow from one quest to the next.
For reference, my previous best time abusing Method-0 in 7.3.5 was 32.4 hours(as show in the old thread). A difference of just over 8 hours; which isn't all that bad, all things considered. And I believe I made several errors along the way, which could be cleaned up in future runs. I believe that that gap could be significantly closed by using a monk's bonus, but I hate playing monk...so...yeah. YMMV
Where you have given your consent and have not subsequently opted out, we may also collect information about what is watched and bought by you, at what price, in what amount or whether did you add specific products to the cart but did not buy them and use it to create a profile of your interests on the basis of content that we think was interesting for you (for example because you added it to the cart) as well as content that other users similar to you have found engaging. By using [this profile of your interests we can adapt our marketing materials by replacing the default content with content more relevant to your interests (for example we can show you games or other products that we think you might like instead of the default offers)

For future reference, it is a great option to purchase mounts and pets as a long-term investment. Not only do their prices scale well even when a new expansion drops, but there is always a demand for them. The only drawback to this strategy is you would need a hefty amount of initial wow gold investment and also maybe have to go through the motions of spending for a guild bank.
Literally just do quests as efficiently as you can. The difference between picking a perfect route and just doing whatever is like an hour, tops. I've already leveled 7 characters in bets because I won't be playing at launch (baby due in aug) and I've been under 12 hours on all but the first. I actually broke 10 on DH, but that's bcuz war mode and DH leech is OP, not because of a special route.
"'Going big' increases your production and decreases your waste. How does one make a lot of cards, though? Since they're tied to a daily cooldown, the options are to buy the cooldown from other scribes, or to have multiple scribes... If you plan to step it up and make decks, though, you'll need to either develop a network of scribes willing to sell you their daily cooldown, or make a bunch of alts into scribes."
This so much. I hate that this happens because I love Prot so much. I can pull so much stuff and not die, which comes in handy when you don't have Legion Loremaster (I re-joined recently, been trying to get it done but y'all know it's not quick). Basically that's the only reason I keep my guy in Prot. I only go Ret when there is a significantly better tank in the group or in PvP.
Even though the value of gold relative to real money plunged during the Legion expansion, we didn’t see corresponding increases in auction house commodity prices, with the exceptions of big-ticket vanity items like TCG mounts. Consumable prices in gold were actually stable or falling during the same period that the value of gold relative to the dollar was plunging by more than 80 percent.
“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?

You’ll need things produced by many of these professions to optimize your character, but you only get two professions you can do yourself. Unless you want to grind on a second character to collect all the reputation-gated recipes for other professions, you will probably need to buy the stuff you can’t make for yourself on the auction house. And if the price of the stuff you need exceeds whatever your questing and your followers are bringing in, you might want to sell some of your own trade goods or raw materials in order to finance your purchases.
I do not recommend going for TBC, although I remember Hellfire peninsula to be decent, everything else is rather slow. Instead go for WotLK, Borean Thundra gets you levelled very fast, and then you can head straight for Icecrown at 67, which is also insanely fast, although admittedly has a few elite quests. You can go to Sholazar Basin alternatively. 2 zones should get you 60-80 no problem.
Un très court paragraphe pour vous dire de ne pas perdre de temps avec les élites rares. Ceux-ci peuvent bien évidemment éveiller votre curiosité et droppent peut être des objets intéressants, mais l'heure n'est pas à l'affabulation pour le moment, mais à l'optimisation, et les élites rares ne donnent pas assez d'XP pour daigner que l'on s'arrête pour eux !

If you level with friends Prot would probably be the way to go so you could pull and face tank the packs. I leveled 2 pallies both ret on beta and had 0 issues. Selfless healer and wake of ashes work absolute wonders. I leveled a bit as prot and just felt like I did 0 damage. I leveled solo so I don’t know about the xp fall off but I would assume it’s the same as legion.
