The magic behind this build is by getting the recurve bow early and using it to out farm your opponent and to prolong your defensive ball(W). The attack speed lets you have your armor buffs longer, reflect more damage back to the enemy and do more damage with your auto attack while you have them taunted. You will make short work of Red and blue buffs. Solo dragons while being healthier and faster than ever. I really recommend you give this build a try.
