I do not know why anyone would argue that there is no need for GP. Every MMO needs admins to patrol and make sure people like hackers and glitchers do not disrupt the game for players. I think the argument here is that there is a need for more mature more responsible staff. Maybe certain measures need to be taken to make sure they are doing their jobs more efficiently rather than "hanging out with friends" and "walking on walls and showing off". Sure there could be improvements made on the staff's part but getting rid of GPs' altogether would just be a bad idea.
