I think that scents are nice, to attract dinos nearby that we don’t see… but I think we need a goat… or a flare.
It would be to attrack the nearby dinos that we CAN see, making them closer and possibly within range. Those inside the normal radius would be closer so we could get a little more DNA darting them, and those outside the radius, but visible on the map would be attracted to our location.
It could be something like the scents, that have 5 and 20 minutes in duration, but something like attract 5 meters, 25 meters, 50 meters and to location.
Users with mobility issues, weather problems or just plain lazy would use it, and it could be sold for hard cash.
