In a blog entry on the official website, Diablo III Senior Technical Game Designer, Wyatt Chang, dropped all the details on what would be coming to the Public Test Realm (PTR) in the upcoming 1.07 patch. Players will be able to duel each other for bragging rights.
While the patch notes cover other topics such as class updates, additions to crafting and other tweaks and improvements, dueling is by far the most interesting and something players have been waiting for since the game launched.
Dueling will support up to four players in a free-for-all mode. The players who want to duel will need to talk to an in-game NPC which will send their party to a special PvP area called The Scorched Chapel, which has four areas for the players to battle it out.
The blog gives a little insight into Blizzard's design philosophy by stating;
The game doesn't keep score and there are no objectives. We wanted dueling to be as simple and straightforward as possible, so we created a minimalist system -- we know that even without rewards and objectives, some players just want to beat each other up. Some matchups may be one-sided, and we don't expect that battles will be necessarily balanced. But that's okay, because dueling in Diablo III is more about kicking ass and taking names in a no-holds-barred sort of way, and this design certainly allows you to accomplish that.
We'll have to see if this addition will hook the players who quit playing Diablo III into returning. It seems to me that while this would be fun for awhile, it may not have much long term appeal. The update should be hitting the Public Test Realm in the near future, so make sure to check it out so you can give them feedback on what you think of the addition.
