Hi! During my time as a hunter at Feenix (I played Priest in retail vanilla), there is one single forum thread that teached me more than any other discussion/theorycrafting alltogether. It's the Elitist Jerks forum thread concerning hunter dmg cycles, by Lactose back in 2006. If you want to start preparing for end-game dmg-cycle perfection already while lvling, I urge all my fellow Nostalrius hunters to read this thread! Hopefylly it will grant as much knowledge to you as it did for me!
