Since patch 2.0, Wizard had only one real decent build, that was Chan+Vyr build, and now was nerfed for no reason and falling behind. All the other so called strong builds if wasn`t hybrid or bugged or playing through some loopholes.
(6) Set:
Enemies killed by Fire damage explode and set nearby enemies
on Fire, dealing 300% weapon damage over 5 seconds.
I remember i can`t even kill a small spider in T3 last time, explode? so unforgetable.
