Totemless Shaman Viability at End Game?

So im playing a tempest strike shaman,

  • Dual 1H Swords
  • Crazy Attack Speed/Haste
  • Lots of Tornado procs
  • lots of Aftershock procs from idols with the crazy attack speed
  • War Cry totem for heal/CC

This is what im aiming for Shaman, level 100 (Release / 1.0) - Last Epoch Build Planner.

Im currently level 80, 1.6k HP, My resists arent all capped yet but im working on that. Im making my way through monoliths fine at the moment.

Looking at the build, it looks like the chest piece only drops from the T4 lightless arbor dungeon,

Has anyone played a similar build before, I dont want to push all the way to 100 to farm the unique chest only to have my build be not viable later on and be a waste of time,

All the top builds seem to use totems or the beastmaster/druid mastery,

Thanks
