Greymane the Grey Man, AA Build

Learn when to best jump in and when to best stay at range. Look for CC tools to be used on tanks then leap onto backline targets and single them out in the middle of fights. Learn to keep an Inner Beast stacked with you level 1 talent so that your Worgen Killer at 16 is more potent and your damage is overall higher. Stutter-stepping and attack-moving are powerful tools for any player to learn, but these skills are necessary for playing AA Greymane. 

NEVER take Viciousness at level 1. NEVER take Insatiable at 4. You 100% NEED Running Wild at 13. That talent offers increased engage, disengage, aggressive, and defensive opportunities and completely outshines every other talent in that tier without question once you can understand and play the grey man. 

Depending on what you go at level 20, try to stay at range if Hunter's Blunderbuss is taken and in wolf form if Tooth and Claw is taken. Make the most of the talent because half of your form isn't being affected by the powerful effects each talent offers.
