I was debating trying a build like this: http://us.battle.net/d3/en/calculator/wizard#lPOSjg!Weg!ZbcZaZ
Using some combination of the following items along with some LoH/C%/APoc gear:
Frostburn (+ Cold)
Magefist (+ Fire) - Can these roll C%?
Axe of Sankis (+ Fire)
Fragment of Destiny (+ Fire/Cold/Lightning)
Tals (+3% Elemental Set bonus)
Maximus (+ Fire)
With this build is there any need for IAS? Will it effect the casting of either spell? Any benefit to going 1H + Triumverate (or Tals for additional +3% Elemental damage) over higher 2H DPS? Any feedback would be greatly appreciated.
