What makes sense about some of the classes of animals?? A Lion is a class 9? It's the same class as buffalo. Why? It makes no sense to me. Why is a tiger class 9? Makes no sense to me. Here are my suggestions:
Lion: Class 8 (A little weaker, it makes no sense for a Lion to run around for 15 seconds after being double-lung'd by a .300 Magnum.)
Tiger: Class 7 (A little weaker, it makes no sense for a Tiger to run around for 15 seconds after being double-lung'd by a .300 Magnum.)
Pronghorn: Class 4 (Either make pronghorn weaker, rounds stronger, or make pronghorn class 4. I can double lung a pronghorn with a .243 and he'll run 120+ meters.)
Wolves: Class 5 (Wolves aren't bigger or tougher than a Pig.)
Bobcats: Either make bobcats class 2, or coyotes class 3. (Coyotes are just a TINY bit bigger than bobcats.)
Axis Deer: Class 4 (Axis deer only weigh around 15-20 kgs less then class 4 deer, this would just make sense as they aren't the same size as a roe deer, but more similar to a whitetail/fallow deer.
