Yeah, check the mp resource library sticky 
Not the best build really. Also, I feel a lot of your builds are sort of over-blown in that you shouldn't have to list "mandatory passives." It should be painstakingly obvious to even the most foolish player that you should only unlock 4-6 actives at most, resulting in plenty of points for passives. Individual builds in this game are of little value as most single-character synergies are simple to the point of being labeled; but cross-class interactions are much less obvious and preposterously more valuable. For example static cage causes perma-stun to enemies being hit by whirlwind. It procs lightning and then (precision?) and leaves you with time to spend mana on barriers or damage spells.
-Blizzard has low utility, chill isn't that good. The DoT is good, but not for it's cost; handling it becomes awkward with high spenders. Also, it takes an inefficient amount of mana to freeze anything with it; by the time they freeze you'll be too low on mana to cast other critical spells, the enemies will already be dead, or you'll be dead. Unfortunately it just isn't a good choice except for that fact that it freely procs frost armor.
-Fade step is a horrible choice on a necro compared to it's alternative, which can do 10x auto-attack damage setting off virulence for fear, frozen, or Walking Bomb and giving you a 2-second invulnerability that breaks aggro. Again chill is fairly worthless.
-Winter's grasp costs 65 mana, over one half of your pool, and only stops one enemy. Again chill is basically worthless, since you can kite enemies without it and it doesn't set up any combos. Except this time you've spent over half your mana pool to do it.
-Good job you brought walking bomb, everybody figures that out.
All of your builds are like this. Horrible resource management, no combos, no team synergy. Obvious choices in passives spelled out.
Having promoted a Necro 6 times, I'll post later.
