Even with Harmony being a self-buff, does it update HoTs that have been cast and not refreshed? With trinket procs and other buffs, you need to refresh your bleed/DoT/HoT for it to get the higher values for crit, haste, and healing/damage.
Never tested, but, from what I read, it updates.
So, if you have a HoT and then get the buff, it updates. If you get the buff then get the HoT, it will have the buff. If you have the HoT and the buff and the buff fall, it will drop the buff from the HoT.
But, again, I never tested to confirm this. Edited, Jul 13th 2011 10:24am by Brisin Edited, Jul 13th 2011 10:26am by Brisin
