It’s quite obvious a good deal of players feel that Overwatch would benefit from having a permanent or at least frequently playable PVE game-mode available in the game. PVE is a really good way to help stave off burnout and provides way more variety to Overwatch. I’ve played quite a lot of the game since I bought it, and I find that Quick Play and Competitive Play can only entertain me for so long before I want to take a break. I don’t get much enjoyment out of the Arcade, either.
From Jeff Kaplan in a Blizzcon 2017 interview:
“We know people want a PvE mode, but when people ask us to make our current modes permanent, we don’t feel they’d be replayable enough.”
Why not allow the players to determine whether they feel a permanent PVE mode would feel “replayable enough”?
Overall, there seems to be very little, if any, downside to implementing a PVE game-mode, yet it would be very appreciated by many players.
