[2.0] Kato's Maelstorm Sphere [Ball Lightning, Lightning-Cold Damage, LL, MoM, 7k+ DPS]

I took a look at your skill tree, and I think I've increased its efficiency quite a bit.

Updated Link

I didn't see why you needed so much %increased life nodes from the tree, unless you're really really scared of chaos dmg. I dropped a lot of the life nodes and increased pathing efficiency.

I also added a Jewel Socket near MoM for the Energy from Within Unique Jewel, which converts all that life to apply to ES.

I picked up the Zealot Oath Keystone, as well as some good ES and regen nodes in the templar area.

I dropped the poor Crackling Speed Cluster, picked up the power side of the lightning wheel (dmg + pen), grabbed arcane vision, dropped the inefficient shadow nodes, and grabbed Doom Cast.

This tree should be stronger, esp if you get that Shav's.
