I just had an experience where the trash mobs in arcatraz were one-shotting everyone in our party. A few of the mobs seemed overly-scaled, but the fire infernals near the last boss were particularly broken. Their meteor attack, which is a targeted (not ground) attack, was hitting for 10k. My character was level 43 and our tank had 6k health on my screen, which really felt like a lot during boss fights.
Just thought I’d report it here. I searched the forums and there’s a similar instance of trash mobs one-shotting things in november 2018. I assume it was fixed and is now an issue again?
As a child of WotLK, it was fun learning that there were a fair amount of mechanics on trash during Burning Crusade timewalking.
