Introduction
I was not sure what I wanted to put here, so my introduction is based on Jame's leveling guide introduction.
This guide is made for FAST leveling through the use of Optimized Quest Circuits. With this guide, questing will be very efficient and you'll not waste any second running around and trying to figure out in which order to do your quests. Follow each instruction carefully and you will see for yourself. The quest choices and order to do them are optimal so that you run as few as possible while doing the most possible, turning several quests at the same time. It will be like grinding, because you'll be killing stuff almost non-stop, besides you'll also be completing a bunch of quests at the same time!
Everything described in this guide can be done solo (beside when I say otherwise). You can, of course, follow this guide while duoing, grouping, it's not a problem, it works too.
You'll realize that I grind a few bars here and there, but that's merely so you're able to accept quests I want you to do before heading back into town! (Ex. Breaking Sharptusk, it requires you to be level 3 and if you don't grind, you'll be about 6 bars from level 3.)
DISCLAIMER: This guide does NOT take into account tradeskills, class specific quests or PvP. It's 100% focused on getting the most experience possible in the shortest possible time while doing a lot of quests and enjoying as much content as possible. Any race/class combination can do this guide. Any complaints about PvP, tradeskills, or class specific issues will be ignored.
Basic Rules
Useful Addons
To get the most out of my guide, you should get an addon which displays coordinates, because I use them to describe locations in my guide (x,y). You can use any addon you like, but here's a very simple one I use.
Recommended
Optional
Below is a list of other addons Jame uses, this is 100% optional though, it's mostly for people who are curious to know which addons Jame uses:
Side Note: In case you don't know how to install add-ons, simply download an addon from one of the links above and unzip it. Then drag the unziped folder in your Addon folder (full path is c:\\Program Files\\World of Warcraft\\Interface\\Addons). Then, restart World of Warcraft and it should be working.
If it isn't working, you might need to log out to your character selection screen and click on "Addons" in the lower-left corner. Tick the box that says "Load out of date Addons". Re-launch WoW.
