Late last year, Blizzard scrapped its current plans for a PvP mode in favor of starting over. Mosqueira said this week that the team is still struggling to overcome several obstacles in creating a new PvP mode, including a limited number of team members for the project, a desire to see PvP at all levels, and a problem with converting the existing PvE gameplay to work for PvP.
"In Diablo, the core mechanics are really built around one character fighting scores of monsters, right?" Mosqueira said. "There's a lot of control, a lot of AOE, and some of that stuff starts to not necessarily break down, but it starts to fray at the edges when you're actually now focused on two people, or four people."
