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.
Before I go ahead and settled this debate for good; I spent most hours surfing the .net to get an idea of what others were saying; if you have done the same you will probably find similar results ~ that in the general publics eyes, WoW Dugi Guide vs WoW Zygor Guides is pretty much even. U also probably found that a few opinions were biased towards the guide they owned. These findings aren’t very helpful in finding an outright winner however; they help show the fact that with what ever guide you end up choosing zygor and dugi guides, you will should be very satisfied!
Cooking benefits all classes, especially melee and hunters (it is a free source of food). Until higher levels, the benefits it provides are almost exclusively stamina buffs. While more stamina is always nice, cooking is not essential to leveling. Considering the time investment required, if you pick up skinning then cooking would absolutely be a wise skill to level prior to hitting your level cap, as beasts often drop meat useful for skilling up.
Determine the gear stats and armor type you need for your new character. For example, a paladin requires Strength as their main stat, and heavy armor (the armor type) will scale as the character scales if they are initially unable to wear heavy armor due to being a lower level. Your optimal heirloom gear set will feature the same main stat as your starting gear.
I'd rather not have to manually re-do all the settings for all my addons in-game unless it's absolutely necessary (since I don't have memorized what the exact settings are I use, so I'd have to take screenshots of them all and then remake the settings to match the screenshots). So I'd rather get some more input about this problem before I try troubleshooting it that way.
I've found the best way to level alts is Pet Battling over by Halfhill in Pandaria. My Nightborne Priest I got to 90 that way (the rest was WoD Treasures, then regular leveling post 100), my Mag'har Shaman I'm at 61 with 16 hours or so played. Having a second monitor to zone out and watch Netflix or whatever helps. I think it's the fastest way to get to 90 personally. I really dislike the leveling changes so I just Pet Battle now.
