Quote from the Community update regarding Arena Breakout
> Over the past 2 months, we’ve seen feedback that the mode is a bit too different from standard Arena, so we’ve removed it from this lineup. We know many of you like the mode, and we do too, so the multiplayer team will continue to brainstorm ways to make it available in the future.
I have an idea. Maybe this is a little too complicated, but it seems pretty simple to me. Just make an Arena Breakout Playlist. And make it a permanent playlist. There, problem solved. It would be available for anyone and everyone who wants to play it.
