It seems like stealth is not a viable option for the monster as the hunters are often just on your tail. I feel like a couple of changes can make it more healthy if implemented together.
 Make Trappers Scan a cone about 1/5 or 1/4 of the map.
-This now makes the ability require some skill/luck which aligns itself better with the other classes abilities.
-This allows the monster to not be constantly identified. (Potentially, good trappers aside.)
-Adds value to tranquilizer darts, sonic traps, following footsteps and just plain observing.
 Make Wraith Abduction have bonus damage based on range.
(@60-80% range +10% DMG, 80-100% range + 20% DMG)
Numbers are made up for example.
-This rewards the wraith for staging a proper ambush.
-Abduction becomes a nice tactical move instead of an awkward way to almost kill a hunter and then get domed.
 Slight time increase / Food requirement
-Monsters with more time are able to stealth walk/ fake paths without wasting time not eating or getting chased -> domed.
-Monsters that don’t stealth don’t get easy evolve. Monsters that ambush properly (and are not rush eating) get energy killing hunters.
