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.
Blizzard has taken steps in recent years to smooth out out the leveling experience — Legion allows players to immediately boost one character to level 100, for instance — but if you want to roll multiple characters without spending money on multiple level boosters, you’ll need to spend time leveling. Thankfully, with the right maneuvers, it’s possible to level a character to 110 in a relatively short time. Here are some pointers for leveling in World of Warcraft, so you can rush through old zones and explore the new.
These meats are usually really cheap, so I recommend to switch to these dishes at 50, but if they are expensive on your realm, then it's better to make more [Rank 2 - Kul Tiramisu] up to around 75. As a general rule, if 1 Aromatic Fish Oil cost around the same as these meats, then you should make Kul Tiramisu because even if you have to craft 2-3 for a skill point, you would still only need 4-6 Fish Oil, instead of the 10 meats.
This includes the “Tides of Vengeance” campaign missions, which continue the War campaign introduced when the expansion launched. Two new island expeditions called Jorundall and Havenswood were also added. Weekly quests also require less Azerite than they did in the past, Mythic and player-versus-player islands award more Artifact power, and new vendors were made available.
"Players can get these powerful items, empower them, and which gameplay-affecting powers they want to use or focus on without feeling like they’re just playing the lottery and hoping they get the Pyroblast Bracers or whatever the magical legendary they need to enable the rotation they want to do," Hazzikostas said. "Instead, they can just look at the dungeon journal, look at raid bosses, see where the azurite armor with the powers they want comes from, and focus on getting that and leveling their artifact naturally, in a much more controlled way."
Today, I finally found out what the real problem was. I have always had the "Enable Zone Map" feature off, but noticed that I had "Enable Auto Zoom" still enabled. I assumed if you turned the map off, the auto zoom would just automatically not do anything. Turns out, every time I moved, the auto zoom was still collecting information and 'zooming' a map that didn't exist. I've turned it off now and my game is perfect - not a single slowdown. The difference is dramatic.
A: We chose to go with the subscription-based model instead of that approach. We've taken the approach that we want players to feel like it's a level playing field once they're in WoW. Outside resources don't play into it -- no gold buying, etc. We take a hard line stance against it. What you get out of microtransactions is kind of the same thing and I think our player base would feel betrayed by it. I think that's something else you have to decide on up-front instead of implementing later.
If you’re jumping back in for Battle for Azeroth, we recommend checking out the big “what to do first” guide from Wowhead. You’re also going to want to brush up on specific advice for your class—both Icy Veins and Wowhead have incredibly detailed guides for all of the game’s combinations of classes and specializations. Make sure you go in and figure out all the new (or changed) talents you’ll be using, and start to memorize a typical combat rotation so you don’t die nearly as much in game’s latest incarnation.
Professions: This may seem strange for a leveling guide, but the first opportunity you get, pick up both the Mining and Herbalism gathering professions. Not only will this allow you to track many various quest objectives on your map, but you also get a fair amount of experience whenever you gather. I'd put it at around 10% of a quest turn-in per gather. Since most of your wasted time in WoW is travel time, stopping to gather ore or herbs can keep your exp/h rolling as long as you don't go too far out of your way. You should only gather if it's convenient, and on the way to an actual quest objective. Don't make gathering your priority.
Blizzard also has a great New Player’s Guide, split into four major sections, as well as its “A Return to World of Warcraft” compendium. And be sure to check out Blizzard’s online forums, especially the New Player Help and Guides forum, where you’ll be able to find more information, ask questions, and engage with some of the World of Warcraft community’s most helpful members.
"Since [patch] 7.3.5 we’re happy with the overall pace of leveling, he said. "If you’ve chosen to start a brand new character right at the end of an expansion, getting a character fully leveled up and geared up to complete endgame content before the expansion ends, there’s always going to be some time pressure there. That’s just part of the nature of choosing to do that at that stage in time."
These guides are completely automated and work in-game, so you can see step-by-step instructions as you play. The guides automatically move to a new step as you complete the quests. You are told where to go i.e. the questgivers for accepting and turning in quests along with where and how to complete the quests. Zygor has more steps and details, which would be more suited to beginners. Dugi condenses the info into fewer steps, but still has all the necessary questing info.
Buffs. Food/Flasks/Scrolls/Potions/Elixirs are a small, but noticeable, buff to your killing speed and survivability. If you have a max level character that can already supply you with cooking or alchemy, you'll be very well off, because the AH is a cesspool for this. I can't really give you specific foods or potions to look for, since each AH is going to have different supplies. Generally speaking, lower level foods are going to only last 15-20 minutes until you can buy the more powerful versions at 60+. Look for anything that adds versatility or your primary stat, and buy stacks for each level range(1-60/70/80/90/100).
