PoE Vaal Ancestral Warchief, gates21 builds

First things first, this is NOT MY BUILD. I saved the POB last league and cannot remember who made it. This build has the advantages of being very good DPS with totems leaching damage for you (which is huge). You just lay down your totems and dodge boss mechanics. I wanted to add a new build idea since I am seeing mostly the same builds being posted. Link to POB
