Unlike Aether setups, vitality lack conversoin options for 2H weapon users. I suggest to switch aether conversion affix for Vitality for extra nuke opportunity.
Another lackluster affix is pierce dmg for Grasping vines. I suggest to switch it for 18%WD for Vines.
+1 to both suggestions
I am fine with the idea of such modifier for PS, but strongly disagree with replacing aether conversion affix for Vitality - it will kill my Druid build! :mad:
P.S: Add one more affix or new item for this purpose seem to be th right way for me.
Torrent is a large part of PS damage, but it can’t be converted by item skills modifiers, that’s that problem.
Some item like gladiator belt that converts globally probably. Or Avenger stick
100% lightning converted to vitality on PS and Torrent - problem solved. Common, Crete, lets do it! We want our big badass red nukes of doom 
Something like this would probably be best. Vitality Brute Force is a nice bonus and Vitality Savagery/Upheaval for other builds too.
