Jaina insane damages

This build is for me the best if you know you will not be focus by dive or high mobility hero, you have unlimited mana and insane burst as soon as you use  [Icy Veins]*   with the reduction armor of  [Northern Exposure]*  which also get the bonus of  [Ice Floes]*  

If you want to focus the tank the whole game you can go Q build 

[Frost Armor]*  you have to take this talent if anyone doing physical damages can go really hard on you ( Zeratul )
