Still a lot of room for improvement/swaps here, and still some fixing to do once PoB is updated. Should be +/-10% on most issues though. This is something between 15 and 40 divs depending on meta and point in league and is pretty good.
The Wither change is immensely strong for totem builds which rely on many hits. Most of this is enabled by this change.
This is just end-game theorycraft so I don't have any sort of guide or anything. Will probably level as split arrow/shrapnel and see what happens.
