Ok… Here is my opinion based on the read you provided. I tested maybe a solid 15 times lightning bolt in many single target locations and timed it well, no matter how i arranged it i saw a los of DPS on a single target rotation… this is what i used as my testing single target rotation that gave me the best dps.
I used talents - 2212222
"/castsequence [combat] Rockbiter, Rockbiter",
"/castsequence [combat] Feral Spirit, Crash Lightning",
"/castsequence Rockbiter, Flametongue, Lightning Bolt",
"/castsequence Rockbiter, Rockbiter, Lightning Bolt",
"/castsequence Flametongue, Rockbiter, Lava Lash",
"/cast [mod:shift, @player] Lightning Surge Totem",
PostMacro={
},
KeyRelease={
"/startattack",
"/cast [combat] Blood Fury",
"/cast [combat] Doom Winds",
I then tested the reads recommendation to use bolderfist and tempest combo and i again lost dps but only marginally. I stayed about 20k less maintained with this rotation than my normal one at 150ms with Storm strike on a sperate key.

Now… when i used hot hand i saw the best dps in both single target and aoe situations. i tried on dummies all the way up to 200mil just to make sure i was getting a solid and accurate scale. At my ilvl with no teir peices and on legendary My macro in the OP still holds as the best DPS for me today. Id like to know with the four PC how the lightning macro scales i forsee that being an amazing macro with better gear.
