1. Players drop some or all of their gear upon dying, which can be picked up by the opposing team. This creates incentive to win, and most people will not be fighting in their top tier gear. This should theoretically raise the price of mid level legendaries, meaning that you will not have to roll perfectly in order to get an item worth something. Also, this forces the losing team/player to go to the auction house and buy a new set of gear, and the winning team to (probably) sell the gear they found. As we all know, there is simply too much gold in the game right now, and every transaction in the AH takes out 15% of the gold in the transaction. The more players are forced to make AH transactions, the better this moneysink will work. This will also allow for people to not be able to "buy" victories, since they will have to risk what they are wearing.
2. (Winning) in Pvp MUST be by far the most rewarding (not necessarily profitable) way of playing Diablo 3. Perhaps there should be gear or rewards which only can be obtained through Pvp against randomly selected opponents.
Botters are able to run scripts because they are up against a computer generated system, and not humans. I feel it would be almost impossible to make a bot that would be any good at pvp, without substantial risk. If players have access gear that is considered top tier, and can only have access it through randomized pvp, bots should in the long run be eliminated, or at least the value of the gold they are generating will become insignificant.
My analysis of what would occur if these are implemented (this is all theory, not yet backed by numbers, mind you):
-Top tier gear would remain expensive for those who wish to continue play the game as it is, but depending on the popularity of PvP, the price could go down.
-Middle tier gear would become more popular, and remain the same price, or increase in price. If a player loses his or her gear for pvp, they must go buy a new set via the AH. The winners will most likely sell their gear via the AH. Each time there is a buyer for the lost gear, the moneysink will effectively take away 15% of the purchase.
-Low end gear will remain unsellable / cheap.
-Non-Pvp Gameplay will become more fun. A player will now no longer need to roll incredibly well in order to profit from legendaries. A player who DOES well incredibly well may still receive a good amount, but hopefully their find sells for less, in order to keep the amount of gold generated equal.
-As long as the rewards from Pvp are highly sought after, bots should not be able to infiltrate that market (bots can't win pvp versus humans). In order for these new rewards to be dropped, the opponent must be randomly selected (so that a bot cannot constantly pvp against another bot over and over).
