Fankly, I think that the MA is like some sort of Darwinian experiment.
The top predators already know everything that works and use it, while others learn what works for them. These others are what one would describe as neitch predators. Their sucesses stem from a limited skill set that works only in certain, limited, situations. Since they are rewarded for their behavior(perk points) and there is no negative impact to them if they fail to make a kill. Unfortunately there is also no impitus to further learn other skills to become one of the top predators. They have a skill that gets consistant results for them so that there is no reason to go through the frustration of learning new skills, and failing to make consistant kills while learning them.
And finally their is prey. Prey has no predatory skill what so ever, and if they do mannage to make a kill it can mainly be ascribed to LUCK rather any skill, learned or otherwise. Any attempt at learning is almost negated by the fact that there are no negative concequences for failure, death. They just "up" again, and again, ad nauseum, untill they learn a skill that will get them consistant results. They then fall into the catagory of the neitch predator.
