Tried out 4x Wizards, wanted to give a brief overview on it. Went with the current flavor of the month build Critical Mass / Wicked Wind. Essentially you get your critical rate up high enough that your main 3 abilities ( Frost Nova / Diamond Skin / Explosive Blast are always up and you just spam them over and over.
It is a fun build and similar to the Witch Doctors with massive stun/freeze on hit, the frost nova's do the same thing, in melee range.

Without spending a ton of gold though it just does not put out the DPS I've come used to on my monks, or from videos I've seen of Witch Doctors or Barbarians. At this point, save yourself the 1-60 grind on this class and try a different one
