Templar Summoner Fail! Can i have some help?

Hello Guys, i tried to create a summoner Templar, but i fail.
Now i`m lvl 52 and i can`t see what i did wrong.

I followed this build here, but now i`m weak, and i don`t do damage.

My ideia was create have 2 itens with 3 gems for summoners:
1st: Zoombie + Spectre + Life
2nd: Skells + Life + Damage

For damage i think about an AoE damage, choosed
- Ice Nova (+ Iron Will) -- I only do 160 DPS (with 160 str). :-(
And Totem + Curse
- Flame Totem
- Vulnerability

I tried to use:
- Power Siphon
but i do 48 DPS. :-(

Can i recover this char?

Up!

If you are still wanting to make a summoner, I highly recommend Prozon's Templar, I got mine up to level 69 before it died.
