Been asking for better linkshell management since beta ; ; I really do hope we get /linkshell message in 2.0 & perhaps not having inactive members show up in the list would be better then logging on and seeing something like 4/89 knowing full well you haven't seen at least 15 of those 89 people since we had to start paying to play.
If SE implements offline = do not show up in LS list I think less people would want to get inactive players out of their linkshells since...well.. those greyed out names wouldn't be staring you in the face every time you checked LS list to try to see if people were on for an event.
