Ethereal Knives dual totems build - atm lvl 68

Hi,

I just want to share my EK build. Please post comments and suggestions how to make it more ... end-game friendly :)

Currently I am at lvl 68 ad I can solo pretty good/fast lvl 61-62 magic, rare maps. haven't found higher lvl maps :(

I've started this build after the latest Skill Tree wipe.
So I've got my gems underleveled, I think now they are pretty much OK.

Note that I am not using all of my gems, just leveling some of them.
EK is 5% quality, Ice Spear is 19% quality (-__-)
Curses: Projectile weakness and Temporal Chains
Temporal chains is 17% quality.
EK with the totem is 1970 dps.
Ice spear+LMP is 900 dps.
Critical chance is 27 for Ice Spear and 21 for the EK.

First attack are dual totems with EK+FC+FP+Totem.
Second attack I use ice spear+LMP.
Both attacks kills pretty much at similar speed, however having PHY and Magic dmg, helps me kill everything fast, and the totems help me survive, by distraction or just casting them and running around enemy projectiles:)

For fun I explore the possibility to use totem+GMP+arctic breath, but I need to link it with Faster cast and concentrated effect and increased projectile...not going to happen soon.

I've made my skill points on the fly, but I think it went very good:


Gear:
My armor, belt, gloves and boots SUCK big time ...
Currently I have mana issues, but I will get the mana point just at the begging of the witch starting point. Good regen and good +%max mana.

Always wondered why people don't abuse EK in a build but was also to lazy to do it myself, i just skimmed through since i don't really have time but really looks nice :)

...Does Doom Cast (next to Chaos Innoc) not work for EK?

Could it works even only with 1 totem? So i can save like 25+ skill point instead of go for the 2 totems.. I'm doing a EK witch too and i'm lvl 35, but saving those 25+ skill point i wanted put 'em on more crit chance and ES.. Do u think is this viable?
