I leveled with lightning storm and tornado when i found the tornado-seeking-target aspect. Worked both fine.
Switched to pulverize at lvl50 because in t3 my tornado setup sucked. Pulverize is fine so far (level58). Can grind nm dungeons fast and smooth and i'm sure this build will bring me to endgame easily.
Maybe i switch to lightning shred or nado werewolf when i find that ****ing cap anytime
