So I tried some EoR builds. First I made based on IK set but it was way to squish for me. I came up with this based on SR set https://www.grimtools.com/calc/mN4g7EmZ decent tanky, not that high sustain. Idea was bind bat to BWC so we can heal in case we stop spinning. MI belt help with bat conversion. Tip of scales was added for QoL energy. Maybe one good rolled MI EoR axe is good for also heal from tip of scales (can try later) otherwise Alladrah was better damage. With this version I made 75-76 many times, but still no deathless run - always dies 1 time 
I am not big fan of EoR in cruci/shards, even with 80% CC res you get stopped by spinning so often which hurts damage and sustain. Not a fun skill for me, it is no near the counterpart skills in Diablo 3 and Path of exile. Heck, even whirlwind skill in diablo 2, a 20y old game, feel smoother for me 
Very fun leveling and campaign build for me though.
