-a zone can spawn a max of say 4 instances a day (#1,2,3,4)
-each char who request entrance gets a flag and assigned the instance id.
This is the only instance he zone into during this instance period (1 day, or whatever the zone respawn time)
Once this char gets his flag, he not get access to other instances of the zone.
This however creates an issue where a guild large enough can split their members into 2 groups and send each of them into 2 separate instances in order to try to claim twice as much loot. This however can be dealt with some Rules, such as if a majority of the guild has already used the instance in the morning, then few left over member can group with some other people to go to another instance, but guild cannot on PURPOSE divide itself into sub groups to claim more than 1 instance per day.
More can of worms
