Currently, Legion rares once killed are like Draenor (non-100) rares - once killed, they no longer offer their loot. The problem with this is that unlike Draenor rares, Legion rares do not have a 100% drop rate on their unique items. While this is only a minor inconvenience for those that drop gear (although it is frustrating to only get one chance ever at a piece of gear), it is a lot more annoying in the case of those that drop AP items, toys, or pets.
Legion rares should either be 100% drop and single-time kill, or RNG drop and daily kill. No one should be locked away from an item forever unless that item is removed from the game. Nothing else does that.
