classes 7 and up rework
In my opinion, I feel that the current health/bleed system for large animals in this game makes them a touch too easy to hunt if you are using the higher powered weapons in game (which should be the case some of the time). I think it might be worth looking into a slight rework of their health and bleeding. This could help open up a little bit more variety for heavier equipment rather then just having the .300, 454, and 600gr arrow remain supreme in most circumstances.
Slight quick kill time increase for classes 8 and 9: If the overall health and bleed rate would change to favor longer tracking then I think it would best if the Quick kill bonus be increase.
Heart shots (depending on the weapon used) should have a 70 - 90% chance to instantly kill, while the 30 - 10% would result in very high bleed rate.
Class 9 check rework: The two shot max requirement should be bumped up to 3. I find hunting cape buffalo to be a little bit more fun if I can send one more round down range, but this would benefit the bison as well as the lions. If we get hippos, rhinos, or elephants then it should be pushed to a 4 rather then a 3 but only if either one of these animals would be added.
In short: I think the game would benefit in the long run if the 7 - 9 class range had a little bit more toughness with high tiered weaponry.
