3.3 CI Arc Mines (Need Help)

So I've decided to do CI arc mines in 3.3.
Right now i have 9.2 ES with tier 2 es rolls on gear, with lots of regen from Pyromaniac + Zealot's Oath interaction and Enfeeble + Temporal Chains + Blind as a very strong layer of defence.

This is my first attempt to do a CI build so I'm asking for help and advices.

This tree needs do be optimized for a ~96lvl and i really don't want to drop a curse nodes.
Maybe i will drop a Whispers of Doom wheel if I'll manage to obtain a +1 curse corruption.
Elemental Focus node is taken as a replace to Saboteur node which will be replaced in 3.3.
Also whats the best way to sustain mana?

Here's a link to pob. Sorry for my SSF english.
