A lot of people still ask me what to reforge for. Hands down, this is haste. Haste not only affects both Wrath and Starfire, it also affects our DoTs. If your item already has haste, reforge to crit. Mastery is a very poor stat for us as we’re not constantly in an Eclipse.
Also, something I just recently realized, was how to determine how quickly our DoTs will tick. Our DoTs tick as quickly as the hasted cast time of the same duration spell. For example, Moonfire and Insect Swarm (and Sunfire once it’s fixed) tick at a 2 second base. Wrath, when talented, also has a 2 second cast time. Whatever your current cast time is for Wrath, that’ll be how often your DoTs tick. Currently you can look at Starfire to see how often Sunfire will tick. With bloodlust and Black Magic, I’ve been able to get .8 second Wraths and .8 second DoT ticks, obtaining 22 ticks in an 18 second duration. The good thing is, while Wrath still clips at 1 second due to the global cooldown, DoT ticks do not.
