I think he is referring to Denova (1) and denova (2) when there are alot of groups in EC. Although as my guild found out the other night this will not fix the lag issues. we were the only people in EC at the time and had continuous spikes throughout the duration of the raid.
Yeah I was referring to world instances rater than individual ones - I was in the middle of a raid at them time so I had to post quickly.
The reason I bring it up is that it is always as its worst when the number of players is higher - on a Tuesday evening (after the weekly reset). There will always be a degree of lag - I just think that they need to do something to lessen it- at times it is unplayable and thats not good for a progression level raid (or any other for that matter).
