It is really simple.
You kill a boss in a dungeon and the boss is phased out for some appropriate amount of time. Until that time passes, you cannot see or kill the boss again.
Once that time passes the boss will be in phase again for a kill. Then it will de-phase again for whatever the timer says.
This way everyone who is doing the dungeon has an opportunity to kill the boss with a chance to loot the boss and get whatever XP they are worth.
As it stands now, no matter what the timer is set at the bots can just sit there and wait it out and kill, kill, kill even when they are not getting loot. This hurts everyone.
