I have been getting weird sim results for EleShaman (and in particular, mastery seems undervalued).
Looking at the Theorycraft wiki, for the 4P bonus (Elemental 4T28 - Spell - Ask Mr. Robot) it looks like only Lava Burst is taken into account, which is an issue, since Lava Burst overloads, from mastery, should trigger it too.
Could you please take a look, and let me know if I’m wrong?
Cheers,
