Orc can be a strong threat-builder, due to Axe Specialization providing a permanent DPS and hit chance increase when using axes. However, what really makes Orc a great pick is that it is also a very good PvP race, and the best PvE damage dealer, making it the best catch-all choice in the Horde. Keep in mind that Blood Fury is not good for tanks, as it causes you to receive 50% less healing for 25 seconds.
*You can also go from 230-250 by making Black Mageweave Boots (3 x Bolt of Mageweave, 2x Heavy Silken Thread, 2 x Thick Leather) x 20. This will cost you the extra Thick Leather, but will also be more likely to sell at the Auction House (due to the Engineering use; Gnomish Rocket Boots and Goblin Rocket Boots, which is in higher demand from Player vs. Player-action.
The vanilla WoW Horde leveling guide you see on this site was originally made back in 2006 by Joana (AKA Mancow, or FuriousPaul).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.
