I don’t know if it’s just me or is this the same for others, but I have been experiencing increased lag since new patch, specifically in dungeons (mythic plus). The game tells me I am still having the same ping around 35ms, but when I press my skills it feels more like 100-200ms or so. Basically it feels like I’m playing on OCE server all the time (I am NA, illidan).
Is anyone else having this problem?
Maybe check on the Technical forum, which is where people generally post or respond to issues about game performance.
Can’t say I’ve noticed it that much, except when I am in a dungeon group, which is generally because the group is US based. As happens most of the time for us down here. But I cope with that, as always.
Aww, you poor possum. 
Lag in AV the first night was horrible but last night, with my add-ons disabled, it was much better.
Yeah, I’ve experienced the dreaded lag, but I was experiencing it in Stormwind on MG. I had to log off because of it. It was unplayable.
I’m experiencing spikes in lag/latency since 11.0.5 as well. It’s been getting worse as the week went.
Yes. Particularly in Dawnbreaker during boss one. And also when fighting the lone spider just outside the city before 2nd boss.
Also noticed it occurred when flying in zones (transition from Dornagal to Ringing Deeps). I took a nice “under ground” underground flight and had to do some DH stuff to get back on top of the actual map.
