Blizzard’s currently investigating an issue that’s causing unintended and unusual team comps in Quick Match.
This is probably a bug that went live with today’s patch in the Americas. Hopefully, the bug will be fixed by the time the patch is live in Europe. Stay tuned for updates!
We are aware of an issue causing unintended and unusual team compositions and are currently investigating. We will post any additional updates in this thread.
Thank you for your patience as we figure this out.
