[3.0] SWT / Shockwave Totem

I really want to play a shockwave totem build in 3.0 and am looking for feedback.

It's difficult to choose between Hiero and Scion (hiero\assasin). The biggest thing Hiero has going for it is the option to use a 6L while Scion gets the 'passive' power charge generation.

ES vs Life\MOM is another thing but it is really hard to fit everything that I want into a Life\MOM build.

All in all I hope this build can scale up to shaper, but I'm pretty inexperienced when it becomes to this. It's a bit disheartening to see so many people go for spell totem + something and the same thing goes for hiero's unreliable charge generation compared to the scion hiero asc.
