This is what I would be looking at currently. Softcore. Updated of the old witch.
I don't know where many of the new items or skills change how it used to play.
Shock nova used to be awful. cold snap as bad, and seems even worse now..
I used to run add lightning and lesser multi on my freezing pulse.
Temporal chains, and elemental weakness. So, weakness and massive slow on targets, then shotgun them in the face with freezing pulsex3, with lit damage to shock.
Long range was +crit ice spears of course.
Ice wall to shut down anything dangerous.
Fork, chain, etc are new supports I haven't gotten a chance to play with yet. well, had fork, but didnt seem to do anything for pulse, and didnt like it on spear, so gave it to the ranger.
Forking or chaining arc? seems interesting.
Used to run wands for spell damage, but thinking of swapping to daggers for the crit. New passive tree seems to have too many crit options to not go for that.
