Eu server spike lag problem?
Pretty sure you and your dungeons groups aren’t alone and its not just limited to Dungeons.. pretty much every world boss event now has it with lots of players complaining about heavy spiking and random disconnects.. I managed to kill Jormag almost 3 times yesterday.. each time getting to around 10-20% and being thrown out and instantly logging back in to find myself in a new map instance… but its not just large zerg events either, I have seen the same issues on Cursed Shore as well and Timberline Falls is just a serious game error waiting to happen within a few minutes on being on map.
I dare say our own internet connections have some part to play in issues from time to time but group wide and map wide lagging/disconnects are just to prevalent since the Sept patching for it to be isolated to just our own end imo.
