I quote from this thread.
Michael Mayhem on the 06/03/16 stream stated: "We have a lot of higher priorities than new or renovated PvP I'm afraid. We are overdue for the regular tuning passes but ultimately, PvP is very difficult for us to do. We have a game where the heroes are super fast paced and fun, and the mobs are relatively slow and cumbersome, which adds to the feel of being a superhero. I often see the "just make a patrol zone with open pvp enabled, its so easy!" but that's actually terrible. Trust me, we've tried. Hitting an extremely mobile moving target wasn't what the game was built for. Even just hitting Doop with certain heroes can be hard and he's awfully slow"
That does not leave much room for speculations about the future of pvp, right?
