changing frenzy to bash with +6 fury rune is good too. dropping owerpover for for warcry was nice for act 2. if you change WW rune then try to get boots with movement speed.
invuln is pain. arcane is OK if you have space to kite. just kill them with cyclones from sprint and refresh BR. wallers are bit complicated but doable as well. sometimes its just about running in circles (if possible around some obstacle)
just few tips from someone who has started using this (to avoid frustration). battle rage is key here. without this you will die as you will not get enough fury. so start with BR, now sprint AROUND mobs (you wont be able to go through them withour whirlwind) in fairly large circle (if possible, harder in dungeons). when you are on full fury, keep sprint up, run towards mobs and hit whirlwind. you will go through them, drop more cyclones, etc. circling around whilst using whirlwind is good too. just dont forget to refresh battle rage. after some practice you will see it works like a charm. if you die its most probably due to lack of BR and no fury. for hard hitting mobs its best to kite them around so they walk into the cyclones. its safe way how to kill them. works nice for fast mobs too.
