I'm going to confirm this ... went to coil t1-t3 on tuesday, the instance servers were fine. Come wednesday when my coil team agreed to do t4, some of us were lagging throughout the fight. I was experiencing 2-10 second lags between mob animations. I thought it was just me at first but some of my coil team were experiencing it as well, only to be confirmed by several of our FC mates doing CT that almost wiped. Hell, I tried to run CT last night only to apologise profusely to my alliance, everything seemed like a bad stop-motion animation. It is unplayable at this point.
