I'm trying to help out an ele sham and just by browsing logs I'm seeing he isn't casting nearly as many lava bursts as our other shaman. Gear is about the same and the lower caster is goblin so I doubt haste is the issue. Just comparing to the other ele in raid, I have 107 casts v. 86. Is there a buff that might affect this besides ascendance and lava surge?

Paion is the sham in question, you can check boboseidon for a much higher amount of lava bursts.
