noooo,. i think the monsters should have a logical loot system, i mean if you kill a monster you should be able to get his skin,bones, and in some cases eyes....and if they have a sword, then the sword too, now if the problem is to become rich fast, then just lowing the selling prizes will do, and of course, if you absolutely make a bloody pulp of the monster u kill, then theres little chance for finding a good piece of fur, or if you scorch the monster completly with a fire spell, then theres no much left of anything^^, like that....
the games with random and 1/100 loot are unrealistic, and to have hight loot, in various aspects. then people can make a living as a butcher or leather worker, so intead of making items apear in a 1/100 rate, i think is better to limit the selling prizes of that particular items, and to make it more difficult to work with them(example: leather working) and also be carefull in the way you kill the monster, to keep the items intact, also youll have to learn how to remove the fur of an animal!!, i mean is not something as easy as it sounds, in the case of bones, blood and meat theres no problem, but the fur should be harder to take, and it would require certain skill(because the fur is the moust valuable part of the animal)so putting this limitations along with this loot system, people wont get rich any time soon ^^....also, not all the monters have eatable meat, and some may not even have furs, as for bones...it should used for armor decoration, trofees and alquimistic porpouses....(and may be a bone armor^^hehehe)
