Blizzard made a few updates to the Mistweaver 2 piece bonus last week. They updated the bonus to include a 5% increase to the periodic healing of
Fonte dell'Essenza HoTs, along with leaving the 2 second duration increase in place. This bonus to the HoT healing of
Fonte dell'Essenza, while nice, does almost nothing to increase the overall power of the spell. The majority of
Fonte dell'Essenza’s power comes from the initial bolt hit and not from the HoT. Increasing this by 5% will be generally unnoticed. So while it does make the 2 piece somewhat stronger, it won’t change how you utilize
Fonte dell'Essenza once you get it. Just enjoy 5% more HoT healing.
