Another important part of optimizing is collecting consumables to use during tougher encounters. Because of how expensive some of these items can be, you’ll probably want to reserve costlier items for raids. While consumables aren’t a requirement, they are another way of making your character even stronger. Taking the time to collect and use consumables shows other raiders that you are dedicated to performing at your best!
In-Game Addon Version of My Leveling Guides: As of June 6th the In-Game Addon version of my leveling guides has began construction! It will be a long road before it's finished completely, so I cannot guarantee how much of it will be ready for Classic Launch but there is a decent chance that some starting zones will be complete for it by then. It will be full of features, including: waypoint arrows, automatic updating, and much more. More features will be available for it overtime too.
The vanilla WoW Horde leveling guide you see on this site was originally made back in 2006 by Joana (AKA Mancow, or FuriousPaul). The guides have been tweaked many times over the years to make things "faster". The leveling guides were made because of all the messages I got from people asking me how I was able to level up so quickly on new realms. I was first to level 60 on 7 different realms (3 with Mancow and 4 with Joana), even winning Blizzard's "First to Level 50" contest they held back in 2006.
