To begin the male lions should get a rework that would enable some type of physical change with the lions difficulty levels for example a 9 legendary lion would have a fuller and darker mane than a 5 medium a 5 medium would appear like a young male lion
BEHAVIOR :
It would give an appearance like the male lions are aging through respawns this would add more depth to the lions and 9 legendary lions would be more aggressive and would ward off smaller male lions like level 7 and below a 9 legendary would make an 8 mythical alert rather than flee like level 7 and below this could also have chance encounters like 9 legendary and 8 mythicals fighting over a drink or eating zone
New trophy mounts could show fights,coalitions , or just two or three brothers that are resting or playing
