The rework questions

I like a lot of what they are trying to do with the rework, but it really leaves me with a lot of questions.

How does Whirling Elements: Air function with Primordial Wave?

Does the Sundering from Reactivity proc Windfury Weapon?

Does the Ice Strike proc count as a Frost Shock for Hailstorm? If so, does it double dip in Swirling Maelstrom?

Does Flowing Spirits generate MSW?

Does Whirling Elements: Earth and Lashing Flames boost Voltiac Blaze?

Do you need to spec into Sundering for Reactivity to function?

Do you need to spec into Hot Hands for Whirling Elements: Fire to function?

Does Totemic Rebound have a chance to proc on each target of Chain Lightning or only the primary target?

Does Reactivity proc Earthsurge? I’m assuming not as you aren’t “casting” Sundering but I could be wrong.

Feels like I can’t begin to play around in the talent calculator without knowing what works together. If this stuff does work together than it seems a bit overwhelming. I just want to know what doesn’t work.
