Was there a hotfix over night that made Spiritborn squishy?

I had 5 new items of gear that were each a 40-90 IP upgrade. Same Aspect on each. Similar Tempering. No significant changes in item stat distribution.

I’m on Penitent, hanging for 60. Things were easy pre-upgrade. After upgrade, my Spiritborn is getting melted. I did the Seething Abomination, previously a routine mob, and I died within a second of landing Soar.

Was there some sort of Hotfix, bug, or did I just make some egregious gearing error?

Edit: I just tried making sure all items have Max Life. Still melted in 2 seconds by Seething Abom. This was an easy mob only 2 or 3 levels ago.

Cannot speak for you as I do not know your build.

However, my QV Overpower build is the same as ever…melts everything tier 4 can throw at me.
