I've just reached a spot in my hunting career where there are some nice flexing hunting grounds for me to play in. The challenge of overcoming a tougher than average creature adds a little spice to an experience that tends to be monolithic.
I'd love to see rare variety creatures that spawn in hunting grounds to challenge the hunters there. They would need a name that sets them apart from the garden variety creatures. This rare critter would have some combination of much more stamina, better offenses, better defenses, stealth abilities, spells, etc. Let these advantages be offset by some weakness like vulnerability to damage type, poor perception, etc.
