I just want a big map instance with all the raid bosses inside. You could add out of combat mechanics such as beating 2 easy bosses that guard a lever each to open up the pathway to the main boss. Each boss would have a checkpoint before the fight that would mark your weekly loot progress. If you leave the instance then you could que back in and teleport to the checkpoint. Imagine defeating Guardian and running up kefka's tower to face off against Kefka. It would really be nice if the weekly loot lockout was individual based or % based so you could help friends.
