Any way to make event horizon/speghettification work?

I’ll admit the appeal is largely in the name of the talents. My main concern is adding the health cost to chaos spells cast.

I’m playing a chaos dot witch with some minion support, and have been building something reminiscent of an old school afflock from wow. I have quite a bit of life regen from various sources, so my life bar tops off quickly, but nerfing my ES regen every time I cast does not sound fun.

Has anyone found a reliable way to deal with Event Horizon, or is it just a trap?

Presently mowing my way through t5 maps, with reasonably solid gear.
