kicking for being inactive can be done by a party leader. As far as kicking for being inactive I am strongly against this, mainly because I party with a group for a long while to build time until I'm too tired tp play any more and drop from the party. Then I go inactive in the zone with about 10-12 hours worth of minutes.
After I get about 5 hours of sleep I start farming the zone til I run out of space in my inventory and leave and sell all of the Dark rings I collected for mega gil. Not forgeting all the skills I get for my other weapons that bst dont normally use like dagger sword and club, as well as parry skills.
