Boss HP bug or intended, official response?

Can anyone confirm this is a bug or “working as intended”, or if there has been an official response to this issue?

You’ll need to be far more specific about which boss HP bug you are referring to.

World Boss?
Pit Boss?
Echo Boss?
The Butcher?

Apologies… pit boss, and tormented… duriel seems fine, but other tormented bosses I’m barely putting a dent in… can kill duriel in like 60 seconds, vs 195 pit bosses, and other tormented bosses are taking anywhere from 3-5 minutes… same with 180 lvl horde
