Personally i don't like Blizzard, so i propose 2 variations that i'm testing:
The first is practically the Malakai's build --> http://us.battle.net/d3/en/calculator/wizard#ZQXhST!gWX!Ya.a.a
Massive damage/healing from Reactive Armor, i was awazed at the beginning; the skills without runes means you can choose the rune you want, depends on your ehp/damage/life steal etc.
The second variation is more "cool looking", but probably less effective --> http://us.battle.net/d3/en/calculator/wizard#ZQXhfS!gWX!YYZac
Fracture+Frozen Storm+Sleet Storm = amazing 3 dancers with 2 "storms" around them on the screen! from my testing i notice less damage than the Reactive Armor build, but it works absolutely.
One thing to note is that i use Autohotkey, so that i can spam "e" for 12 or 123 spells, and "r" for the right click spell (this one is REALLY useful, you can keep spamming the left click without moving your fingers from left to right; i use autohotkey's scripts for every build i play, i won't live without it).
I tested these at MP6, when i'll upgrade my items i'll try at MP7.
