So I run poison druid, and most of the time, damage is applied and consumed too fast, that it does not render what is actually happening, but D4s servers melting actually slowed my damage down to where you can see what is actually happening. For reference I am using a 2.2s Barber, for speed farming.
In the clip im, not fully setup with my paragon and gear, as Im testing other things but it shows poison druid is still viable.
