As has been said numerous times the conditions required the meet the necessary threshold for the ability to remove someone from a linkshell to work are so completely counter intuitive in a situation where you would want someone removed from a linkshell to begin with as to make not even the slightest shred of sense.

It is so far removed from good and common sense that it functionally does not exist. That is to say there is no real difference at this point between having no command at all, and having the command as it is implemented. And so, it needs to be implemented as soon as possible. Even if it is only that command for the time being, as it is fundamental to the administration of a linkshell to be able not only to add, but also remove, members at will.

I should simply add that it made no sense from the outset that any LS command should be bound by proximity to other linkshell members except for the actual trading of the pearl to that member upon entrance into the LS. Especially given that LSs allow players to communicate freely across the whole of the game regardless of location. Conceptually speaking LSs aren't a location centric means of socializing, and so the commands associated with them should follow suit.

Three paragraphs longer than anticipated. In short, get'er done.
