I am guessing that those Rogues were from a patrol path that is very rarely crossed by players when the server is not well populated by players.
I was on earlier today, and I did some missions to see what affect it might have on the server. I am pleased to say I saw nothing resembling the lag symbol at all during those missions, and everything proceeded smoothly, except the 5 Bounty Hunter destroyers I had to kill in my Raven's Talon (with a Train CD...). That was a pain. But I noticed a lot of Titans hanging around Crete and when I was on my way to and from missions.
I just wish we could keep the processor installed now... but I am sure that as always in the computer industry, something better will come along quite soon.
