For each character level (up to 60), there will be 5 levels worth of weapon skill. This means that each different weapon skill requires 300 levels on a level 60 warrior. The reason why this matters is because of how glancing blows work on enemies. The basic concept behind weapon skill is that a higher weapon skill will result in less damage lost. With a lower weapon skill, your attacks have a chance of dealing reduced damage.
The great thing about talents is that everything is up to you! You’ll find a few recommended talent tree choices below, but feel free to move points around as you feel necessary. Depending upon the fighting situation you’re going into, you might want one set of talents over another. Take time to understand what your purpose is, which will help you decide what talents you’ll need to help achieve that.
The vanilla WoW Horde leveling guide you see on this site was originally made back in 2006 by Joana (AKA Mancow, or FuriousPaul).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.
