This build makes Illidan very similar to Artanis in the way that continuing to attack helps you stay alive in a fight. Right from the onset everything you kill is adding to your basic attack damage so be mindful of the fact that you are always getting stronger. Once you reach 7 and beyond the general idea behind the build starts to shine through. By the late game you will be hitting very hard while healing for viable amounts. Makes Illidan a major asset in late game team fights.
