Nifty stuff!

I am just starting a 5x Shaman team myself this week for PvP fun, so there's a lot of good info and stuff to mull over in here.

Some thoughts though ~
Seems you're using Focus to assist off of, yet often also including a physical /assist? Why is this? Seems redundant for casting?

I have a hunch it's for clones to get in on the melee action, correct me if I'm wrong?

If that's the case do you use TwoBoxToolkit addon, and enable sticky follow? Again, my little shammies are just level 10 so far from a night's work, and I found clone melee a pain in the ass tbh, being that I broke follow always, and ticky follow within TBTK addon is kinda clunky when you get into switching mains. But, I digress ~

I've never used a BIG Button myself yet, I've found that a combination of Automaton & TwoBoxToolkit handle rezzing, grouping, quests fine enough. Thoughts?

Your totem sequence. With a hard number reset, do you ever find you goof on your sequence? Would a reset=combat work better?

What is the point of harm, nodead, exixts etc in an offensive spell? I haven't got any of that on my PvE team of casters/hunter... I guess I assumed they get errors and just not cast, then carry on fine. Am I missing out on something important? Perhaps it saves a GCD? Ugh, enlighten me, I have a feeling I've been a big nub all this time.

I'm sure I'll have 450234819 more questions as I progress, thanks for your share though, tres helpful~
