PLEASE NERF! Drowned City - Sea Witch - Water Bubble

Please nerf the Water Bubble of the Sea-Witches in Act 3!

Its just dumb, that it kills you instantly after 2-3 seconds.
If you dive under the Water for 3 seconds you dont die neither.

Instant Death just dont make sense on a NORMAL MOB.
Imagine having ~2000 life and 500 energyshield and die instantly on HC to a Mob you can actually 1hit.

I died to it while being surrounded by 2 Elite Packs with Ice Bombs and Lightning Bombs. It was the first encounter with the Bubble and i just had to find out the hard way, that i rather risk taking damage from the Elemental-Bombs than dying to a Water Bubble.

I am not the only one who died to this.
Have found this video on Reddit:

My Suggestion:

Make it deal Damage over Time instead of a instant Death.
A Mechanic like this belongs to an Act or Map Boss, but not to a normal white Mob.
Otherwise make it like 6 seconds and let the whole Screen Blurr untill you really cant see anything.
