So Im 'Tornado' !!!
Ive played with other HotA runes , and with Seismic slam, all work pretty fine but smash is awesome on elites. Rend/ravage works on weak enemies like spiders etc that come in masses, leap helps u jump in middle of those and rend all of them with one blow, giving u bonus exp aswell.Bash/punish beats frenzy and gives u also nice single target dmg on the other fury spenders. The dmg u get is very good even for mp7+ but survivability is not so good, Id recomend this build for farming mp4-6 in a fast pace. Also instead of bloodthirst passive i use brawler thats amazing
