if you remember in XI, you have mobs that tracked on several different senses, as well as agro. Its no different here, Ants agro sound as they should, so you can just walk past them, and most other things agro sight. If a mob that tracks by sight looses you... why should it not just loose interest. Thats what they did in XI. Also although there are no scent tracking mobs in XIV as there were in XI, when a scent tracking mob like Orcs... for example agro you could simply run through water like you could do IN REAL LIFE wonderful concept and they would stop chasing. Just saying ^^
