map completion feedback

I'm not a fan of the current rare/boss kill completion.

So here is my suggestions.
have a hunt system.
you have a timer to hunt the rares and boss for a bonus something(extra rarity drop rate?) timer passed all is visible on map.
maybe add a part to the atlas for hunting points
like a note - add a compass aura to track rares for -10% rarity drop


have a nice day.
