As much as I agree that this issue really needs to be fixed, considering their answer on the 24th August (just over a week ago) I don't think bumping this thread is going to shed any more light on their plan at the moment :(

"The dev. team is well aware of the issues with the linkshell list and friends list, but it’s going to be very difficult to address in its current state. Therefore, the devs are going to be performing a complete overhaul of the system. With this overhaul, the team is planning to add functions that have been previously requested by the community. These functions include LS messages, the ability to remove players from the linkshell, more variations of LS crests, etc."
