Heirlooms: Heirlooms are the best source of bonus XP for leveling. All slots can be gotten pretty easily now, except the rings. The time you need to spend to get the rings if you haven’t gotten a level 3 shipyard in WoW is way too long, so getting the rings is generally not worth it. Having all your heirloom gear will boost XP by 55%. Generally, you want heirloom gear with crit on for leveling as you want to kill mobs in a few hits as possible
In World of Warcraft: Battle for Azeroth for PC, there will be a stat squish and item squish to lower the numbers used in the game, an example being a legendary item scaled for Antorus: The Burning Throne (the final raid for Legion) being reduced from item level 1000 to 330. Unique buffs are added back; these buffs are class specific which are mages’ Arcane Brilliance, druids’ Mark of the Wild, etc. Titanforging—something that allows for an item to be more powerful than normal—is still in World of Warcraft: Battle for Azeroth for PC; however, if the item is one of those affected by the Heart of Azeroth, then that item cannot be titanforged.
Tiragarde Sound and Stormsong Valley are both fairly similar zones, but Stormsong is a little longer, meaning that you might not even have to finish it to hit 120. Tiragarde also comes with a bit of a warning. There are plenty of side quests to do in the zone after you finish the story quests. Don’t do them. It’s not worth the time or the experience you’ll get.
Although the Battle Pet Trainer will only offer to teach you your race-specific companion, it is possible to add all of these pets to your collection. You can either find them in your faction’s auction house or you can create a character of the race whose pet you would like to learn. Using your new character, you can seek out any battle pet trainer in major cities. After you learn the pet, you can delete the character; the pet you learned will not be removed from your collection.
":" - Any time a step ends in a ":" instead of a "." means that the next step is part of the current step you are on. This generally means the next step should be done while working on the current step. This means every "start working on" or "continue working on" will end in a ":". But this is used with other occasions as well, so keep this in mind.
After 14 years, the biggest problem for Blizzard is to keep players engaged. The war setting is a way for the developers to return to a primal conflict and create emotional touchstones. The Nightborne have turned their backs on the Alliance; Sylvanas has destroyed not one but two cities; the Kul Tirans have cast Jaina Proudmoore out as a traitor; and Taelia Fordragon is starting to ask questions about her father, Bolvar, whom she has been told died in a war against the Lich King. (She does not know he has become the Lich King.)
I'd say level this toon a bit more, maybe up to 30 or so, and see how you like the experience. If you find questing just a means to an end, maybe the guide would be a good buy. Me, I generally like questing and go to an area I'm interested in, even if it's not the most level-appropriate for me or the best way to maximize my time, so those guides aren't of much interest to me for now.
Most of the time you spend leveling will involve questing and slaying monsters, but there’s also a lot of travel. Travel earns you little experience (you do gain a bit for discovering new areas), so it’s wise to keep travel to a minimum. The new level scaling system, which scales zones to your level within a preset range, helps with that. You can choose what zones you want to experience and stick with them until you finish their quests.
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.
