The current timer on guild ship buffs to 6 hours or until death. The game has spread out since ship buffs were introduced. There is absolutely no reason for ship buffs to last 1 hour. It's hard enough getting a PUG group together, there's no reason to make everybody go back to the ship every 30-45 minutes to rebuff. Because that's what happens. If there is any doubt about buffs lasting, it's rebuff time. A 6 hour timer would allow just about all players to just play through their session and not worry about buffs unless they had died.
