So you want to be a Hunter? We have you covered! There are countless resources scattered throughout the internet, but here are a few of the more reliable and comprehensive sources that are current as of 7.2.5. If these resources aren’t enough, you can always reach out to one of the many guild leaders who play Hunters like Cowculator, Noraline, or Shotindabutt. They are very willing to give you some time to discuss their understanding of the class.
