For me the issue seems to be way worse and random in Raids.
It feels like I am playing Russian roulette when I join something.
I was lucky to finally get a relatively clear Second Circle - Savage run to clear ( I still had brief lag spikes tho ).
But before that I did the weekly normal ones and two of them had insane lag in the Third Circle my game just froze for like 30+ sec after the boss was killed too but I had spikes throughout the whole fight.
I dunno if something is just wrong in particular instances, I've had the same in some Second Circle - Savage runs where everything seems fine, then we pull and I immediately as soon as I enter combat feel the lag happen/ it freezes.
