Say what you will about Diablo III, it doesn't change the fact that Blizzard is one of few developers 100% dedicated to their product for the duration of its lifespan. For example, introducing patch 1.0.7, coming more than half a year after Diablo III's release. The patch will add player dueling, including a new area called The Scorched Ground made just for duels, and a ton of additional content and quality of life changes. 

Without going over every specific change or addition, here's a shortlist of the highlights from patch 1.0.7:

• The Scorched Chapel: Dueling - 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.
• Stay Classy, Sanctuary
  • Wizard -  The Wizard is seeing a damage buff to skills such as Arcane Orb, Blizzard, and Shock Pulse.
  • Monk - The Monk is getting a big damage buff to all Spirit Spenders.
• Item Hunting
  • New Crafting Recipes - Set of Rare crafting recipes that will create account-bound gloves, pants, wrists, a chest piece, and an amulet.
  • New Gem Tier - called "Marquise" and most of its stats are in line with the current gem progression
• Monster Power Changes - Two clear areas where we can improve: making Monster Power available in Public Games, and increasing the XP bonuses for players in Inferno.
• Monster Changes 
  • Reflects Damage - Monsters with this affix will now pulse a damage reflection shield on and off.
  • Molten and Plagued - Reducing the damage from Molten packs and increasing the damage from Plagued.
• Quality of Life Changes
  
  • Removing the incrementing resurrection timer on consecutive deaths.
  • Increasing the base pickup radius by a small amount.

All of this should be coming to the Diablo III Public Test Realm soon, and depending on how it tests we'll hear about a release date in coming weeks (it might even be on the PTR by now). 

While the dueling system may not be anywhere near the PvP Battle Arenas many players were looking forward to, that has unfortunately been canceled, it's still great patch content. Hopefully Blizzard's new PvP content in the works delivers everything fans want and more. In the mean time, Diablo III's patch 1.0.7 sounds great and should reinvigorate the community for some more Infernal Machine farming.
