Mortar Trap Elementalist(?), who's up for the challenge?

What about Grenado or CD Stun Jacks? They work well on my elementalist even against single target

CD Stun Jacks would be nice, Grenado is awesome but it needs high skill number dedication in order to be good, and you dont actually have skill points to spare, especially in Elementalist.
Are you suggesting MT+ST+WD+SJ+Grenado build?
How would you do it?

I liked the Purifier idea because of Mythical Anderos Amplifier, but I cant get enough information for RoK damage or gameplay, and I dont know how to utilize it in the best way in a build like this.

What fix are you referring to?

saw something in the patch notes about it, didn’t seem to make much of a difference. Unless the damage is tripled, it’s still a weak skill for the investment

v1.1.1.2 anything else?

Mortars have been strong in recent patches,but why you go with Elementalist instead of Purifier?
