I've also been having lag spikes the last couple of weeks. I especially get 90k'd in Eureka, in normal dungeons it's simply lag spikes that really mess with my skills.

-PC
-Delay lag (such as people will stop moving then move again and skills won't activate when used. These issues are even worse in Eureka.)
-Wired
-Discord, steam and google chrome
-Restarted router and computer. Tried without apps running in the background, issue still exists.
