I was thinking of the flame shock because of the Storm, Earth and Fire talents (+50% periodic FS damage bonus) But I could easily leave it out.

I guess, I'm just trying to condense some bar space. Currently, I have [nomod] LB; [shift] frostshock; [alt] earthshock; [ctrl] flameshock on one macro, and all my regular PvE/instance totems on another castsequence macro. Then I have my PvP earth/air totems on a macro (these are usually all or nothing, like everyone drops a grounding, tremor on ,,,, cast sequences and earthbind) and another macros for just fire damage spells (fire nova, searing, magma; again everyone drops the same one at once)

My chain lightning is on a macro with elemental precision (since it's off GCD) and modifiers to cast the new windshock or castsequence for thunderstorm. (having an issue with the castsequence macro, will rebuild later)

As a side note, how do you other shamans heal? I've got 5 macros, 1 for each party member (HW is nomod, LWH is alt and chainH is ctrl) which usually results in massive overhealing if everyone is alive, and ensures that if any are dead, at least they'll cast healing on the right person. Any tips for that?
