I had Lancer vs Lancer in my playlist and never found a game. However the second that Ranked Practice came online I was immediately put into it. The problem is that it was hot-swapped.

I was expecting to never have a control game in my playlist and then suddenly I'm thrust into one that's 4v4.

Featured gamemodes should not be hot-swapped that way, because for the play experience they aren't interchangable.

They definitely shouldn't be swapped before your public announcement of it either.
