Hi. Not a bad guide for sure. But your level 13 and 16 talent recommendations are utterly useless. At lvl 13 chainlink. What for man? You cant combo so often due to the cooldown of Shadow Fissure so why would you want a reduced cooldown of chains? If you were trying to help your team with just cc with no real purpose for your own combo then chains pf ice are still better thanks to the slow so allies can catch up. And level 16 talent hungering cold as a recommemdation? You cannot be serious. You never hit your enemies more than 3-4 times during your combo after you cast frost nova. So t adds very little damage. Whereas increasing the damage of your shadow fissure by 30% does more dmg (combined with the proper level 1 talent barbed chains) is an absolute killer. Hungering cold by definition goes against everything KTZ is. A ultra burst combo mage. Basically doing nothing until he comboes where he annihilates anything. He is not a sustain damage mage. Otherwise a okay guide.
I also noticed about 5 sentences that look as if copied and pasted from my guide but I will not do any assumptions.
Take care.
