Well you're sure as hell not trying to contribute to the discussion.
Theorycrafting is good but
I am posting some screenshots of my dps in an actual boss fight. (i am not trying to brag :P)
with 4tier6 on me, elemental/enhancement spec (actualy 17/44, i do some pvp too )
and yes! my following DPS results in two bosses at BT are with TOTEM TWIST spam too!
Mana problems? in whole BT i may use once or twice a mana potion (Bloodboil mostly, where i safeguard my shamanistic rage for Fel Rage on me). A wise use of Shamanistic rage makes mana problems obsolete with ele/enha spec and totem twisting, even when your raid power pulls to make the run faster.
Boost on group? Best possible, Rogues are in love, so are warriors, but especialy the rogues get a significant boost.
So the screenshots are from Najentus, 1st boss at Black Temple and from TeronGorefiend 4th Boss at BT
As i said, my current spec at armory is the spec i use at the raids too. I also totem twisted, i wouldn't suggest it without 4 items of tier6. The rotation i used is
Start autohiting, placing Strenght/searingtotem/mana totem, [Stormstrike/Flameshock/Windfury-Goa(totemtwist)/Earthshock] and again [Stormstrike/Flameshock/Windfury-Goa(totemtwist)/Earthshock]
If you have very low latency then when WF timer of your addon goes to 1or0 you will be ready on GCD to redrop Windfury/Goa Sequence/macro. Even with my 250ms the 1second my group lacked WF buff was insignificant compared to 8seconds of GoA, especially for rogues. If theorycraft proves the opposite then do what i do only at >100ms latency then.
I wasn't satisfied at all with Enhancement/Restoration in terms of rotation. There was no "harmony" on the cooldowns of shocks and totem twisting so i decided for 1 week to test Elemental/Enhancement but with my 4 tier6 gear on. I may be one of the very few, if not the only enhancement shaman who used elemental/enhancement spec and totem twisting.
About my personal dps, i have to admit that GoA totem for 7 out of 9 seconds is very very welcome. The truth is i don't want to stop totem twisting now. Until blizzard deals with it anyway.
I don't think enhancement shamans at high end gear should be enhancement/restoration. With 1-2 high end leather items and 4 tier6 you can get a 200+ hit rating from gear, making the 3% nature guidance not-so-important and making the elemental tree more interesting.
