Below we list some of the Pros and Cons / Strength and Weakness of Leveling the Warrior Class in general. It’s worth noting that Warrior is one of the hardest Classes to Solo Level up in Classic WoW, you will want to find someone to level with. If you have a hard time finding some, try to Spec Protection and Tank Dungeons and other Farming areas with someone and share the XP with them.
Others – The consumables mentioned above are often considered essential. There are still other items you can acquire to optimize even further, but aren’t as important or impactful as the ones mentioned above. You can benefit from Scroll of Strength, which gives +17 Strength for 30 minutes, or Scroll of Agility, which gives the same amount of agility instead. These are random drops from enemies and chests, so farming them is unreliable.
The vanilla WoW Horde leveling guide you see on this site was originally made back in 2006 by Joana (AKA Mancow, or FuriousPaul).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.
