So pretty much the day after Harrowstorm dlc went live this issue appeared. What does it look like? You just enter any e.g trial instance, and as you progress in the content the latency begins to rise without any appearant reason. Telegraphs appear 2s after they should, some mechanics are skipped alltogether, or you die to it, even though it happened several seconds earlier.
Here is some video footage of what im talking about.

Can we have an estimation on when this issue is going to be addressed? This is really irritating and frustrating, that you cant play whatever dungeon/ trial properly because of this issue.
