Personally, I think someone should add the world "all" in front of default since I think this makes the most sense for the game. However, I'm still split opinion-wise because for all I know, someone might have already tweaked other game settings in their times. In this case, simply changing it to something like, "You must use best-of-three fights, 30 seconds per fight, and 5 barriers" would work. Either way will work from a gameplay standpoint. Heck, you could probably even add more categories for certain settings if you really wanted to.
