Maybe they could make a game type that would allow Hardcore characters to duel without dying forever. I know that would be interesting to a lot of players.

Perhaps they could invent a new game type, where you check a box that says "Competitive Play". After you check the box, you can choose game options, such as the number of players, type of gameplay, arena type, team sizes, and round lengths. And since Competive Play would be set in a set amount of area, it would allow more players to join the game, meaning MORE carnage.

They could implement a gladitorial arena in each major town. It would be the same as going outside of town to duel, only you'd be in an arena and they would have things like a score keeper and perhaps some obstacles or even objectives for the other person/team to use. Instead of sitting in a chat room back on B.net, you could join the crowd in the arena and perhaps place bets on the players, or just sit afk and watch the duel.

I would enjoy it. I think it would be fun - especially in a Diablo world. You also have to remember that the max amount of players in Diablo III may very well increase from Diablo II, perhaps going to 10-12 or even double to 16 per game.
