The recent teq fight gave me this idea.
Allow guilds to research and create a guild instance of a zone of their choosing by spending influence. When used, the creator will be instantly moved a new instance of the current zone they are at. The zone will be opened for only 3hrs. There will be only 2 ways to get into that zone. Any members of the guild can choose to move to the instance if they go to the zone. Players in that instanced zone can also taxi non guild members in.(To allow for collaborative efforts) Both provided if the instance is not already full. The instance must also be cancellable to allow for a new instance to be open or for whatever reasons.
This will reduce frustrations from having afkers and improve coordination for boss fights.
