Before 2.1 (before the servers required us to select the corresponding data centres specifically) I was able to dodge the entirety Titan HM unscathed.... Since 2.1 "rubberbanding" has caused more than a few deaths on my part (even in lesser difficulty Dungs./Raids let alone XM) I am sad to admit. This is not an isolated incident, no matter how close to the Datacentre you are are geographically. (I myself am only 8 Hrs drive from Montreal). My hope is that many people bump this thread so we can (possibly) get a response from the Dev team.
If not, C'est la vie. Ill keep playing because love this game, I just cant stand dying to "rubberband lag".
