Overwatch’s beta is taking a break. On Dec 10th Blizzard’s team-based shooter will go offline for an “extended” period. The break is temporary; the beta will return in mid-to-late January. Blizzard plans to use the time to make improvements to the core game and work on features like spectating and progression.
I think this is a good thing for the game despite being incredibly frustrated that I won’t be able to play it for a little bit. Overwatch has been great for me so far, but it also feels like it needs a big push in the right direction, and I think those kinds of updates only happen incrementally when you have to maintain/respond to an active userbase (see: League of Legends).
