Spiteful Curse Necro setup [WIP]

This is a roughdraft on what I'm trying to form into a build combined with Feast of Corruption, Conditions, and warding [perhaps].

16-Curses
11-Domination
7-Soul reaping

Spiteful Spirit [elite]
Insidious Parasite
Empathy
Backfire
Mark of pain
Rigos Mortis [or efeebling blood]
Desecrate Enchantment
Rez signet

This is the Spiteful- Attack-counterer [I like to use this term] The name explains what it does, it basiclly in almost any situation: Causes a negative reaction when the enemy does a move. I tested this setup in many team builds [iway, ranger spiking, eoe bomb, etc] all of them which accepted me as a random player due to my name :P. I find that many targets I focus on notice the hexes and either keep working at a bad pace or just stop doing anything all together.
Only problem is that it depends on the targets to cast or attack. and Energy management.

I am still working on the rest of the build but I do plan to squeeze in
2 Feast of Corruption Spikers
1 Virulence Conditions Necro
1 Ranger Interrupter + conditions
1 Martyr
2 healings monks

[WORK IN PROGRESS]
