http://eu.battle.net/d3/en/calculator/wizard#acWQXg!gTU!YZaYYZ I'm not that good with hardcore builds, but I guess this is my shot at it. Please correct me and bash me as much as you can, I want to make it hardcore
o yeah, the idea is to slow opponents and then throw the meteor at them. Magic missile is for keeping the mana up and the rest is just slowing the enemy as much as possible.
So I made acouple of changes that I would do. I do like Magic Missile with Attunement(Golden Runestone) as a skill you use when Arcane is getting low or a filler attack but I did change Ice Armor with Chilling Aura(Indigo). I know you were going for another slow effect but you got plenty so I changed it to Diamond Skin with Enduring Skin(Indigo) adding 9 seconds to the duration, absorbing up to 14828 damage is something that will help in PvP battles. The last thing I changed was Illusionist its not required because your not using Mirror Image or Teleport in this build, so I changed it to Evocation reducing all cooldowns by 20% will help you recast those bad ass skills to dominate your foes. You can see the changes here: http://eu.battle.net/d3/en/calculator/wizard#aVcSjO!dTU!bYZZYc
Curious as to why you have the passive skill "Illusionist" when you don't use "Mirror Image" or "Teleport"
