Ancient Parthans?

I see WD’s in top ranking 4man group meta runs use ancient parthans… with zero damage reduction now coming from soul harvest stacks, doesnt it make the WD prone to getting one-shotted during the moving between mobs packs where there doesnt seem like there’ll be any stunned units? Or do they glue themselves to the barb at all times and hope the barb stuns regularly while moving from sanc to sanc? Even when standing in sanc surrounded by a ton of mobs its hard to imagine that there is 100% uptime on stunned mobs and at some point if you’re unlucky to have none or too few stunned you’ll just die, Also, would they take the cheat death passive when using parthans to allow room for error?

Hoping to get some input regarding the playstyle from WDs with experience using parthans 140-150s thanks!
