Dudes! (And Dudettes) elemental DPS and castsequences are simply not worth it!
I've been messing about with these ever since I was level 75. Testing various haste/crit. But in reality, they are almost impossible to apply to PvE.
Extra healing, moving around, changing targets, all make long castsequences that are cooldown based a pain. All mostly upsetting the cooldowns so much it's not worth it. The only reason castsequences seems good for is for when you get in that situation when you do still have thge cd's and need to totally nuke as much as possible, or a few fights where you do indeed not have to heal/move. Patchwerk in naxx for example. Or when testing dps. But with the vast amount of various tactics needed for pretty much all five man and the lack of hp on trash causes castsequences for us to be more of a pain then to be effective.
/castrandom is as close to effective as it will get, but even then you would stumble upon problems with changing targets, blowing flameshock cd's on low targets and lava bursts on flameshockless targets. The problems come with the AI needed to apply flameshock at the proper targets and the timing on the lava bursts.
So I've come to the conclusion that it is pointless to try and make an effective one button dps for us elementals, because it's simply not happening. Stick to 4 buttons and your overall dps should increase. If you have a tank and 4 shammies, try minimizing the buttons needed for your tank instead, while proper dpsing with your shamans with Flame Shock, Lava Burst, Lightning Bolt and Chain Lightning in individual buttons/modifiers. It might take a few days, to get the feel to it, but eventually I'm sure yoú'll be able to dream your flameshock cd's/timers and lava burst cd's!
Just wanted to say. :P
