just started having the same issues described here, never had any lag at all up till now. things have been buggy ever since the last patch was updated and now instance dungeons like AK and Cast M are having moments of pause where everythings stops moving (except me) then resumes moments later or I pause and move in the same position I was in while casting. This is a very bad thing for heals as we have to react to things that happened after the pause has resumed some of which can be wipe worthy.

I hope this issue is addressed or something as its pretty much hindered my ability to proceed past HM Titan and to BCOB and my relic
